Answer:

The order of reaction is as follows, R1 = 1; R2 = 2; R3 = 0

Explanation:

The rate of a chemical reaction is the number of moles of reactants consumed per unit time or the number of moles of products formed per unit. the rate of a chemical reaction is affected by the concentration of reactants

The relationship between the rate of a chemical reaction and the concentration of its reactants is given by the rate law or equation.

Generally, the rate equation is given as;

Rate = k[A]ᵃ[B]ᵇ..., where k = rate constant which is independent of concentration of the reactants, [A] = concentration of reactant A, a = order of reaction A, [B] = concentration of reaction B, b = order of reaction B.

For the given reactions R1, R2 and R3

For R1; rate = 3, Concentration = 3[A]

3 = k[A]3ˣ

3¹ = k[A]3ˣ

Since rate is proportional to concentration, therefore, the order of reaction, x = 1

For R2; rate = 9, Concentration = 3[A]

9 = k[A]3ˣ

3² = k[A]3ˣ

Since rate is proportional to concentration, therefore, the order of reaction, x = 2

For R1; rate = 1, Concentration = 3[A]

1 = k[A]3ˣ

3⁰ = k[A]3ˣ

Since rate is proportional to concentration, therefore, the order of reaction, x = 0

Therefore, the order of reaction is as follows, R1 = 1; R2 = 2; R3 = 0

If the reaction vessel initially contains the N₂O₄ concentration of 0.0550 m at 500 k , the equilibrium concentrations at 500 K of the  N₂O₄ is 0.0115 M and NO₂  is 0.0769 M.

                -2x                 + 2x

Eq.       0.0500 - x            2x

Kc = [NO₂]² / [ N₂O₄  ]

0.513  = (2x)² / 0.0500 - x

0.513  = 4x² /  0.0500 - x

x = 0.038

Therefore, the concentration of [ N₂O₄  ]  = ( 0.0500 - 0.038 ) = 0.0115 M

The equilibrium concentration of [NO₂] = 2 (0.038) = 0.0769 M

Explanation:

In 1 mole of  K2C2O4, there are 2 moles of potassium(K), 2 moles of carbon(C) and 4 moles of oxygen(O).

A mole is a unit of measurement in chemistry that is used to express the amount of a chemical compound. One mole is the amount of a substance that has the same number of entities, such as atoms, molecules, or ions, as there are atoms in 12 grams of pure carbon-12.

This is known as Avogadro's number, and it is roughly equal to 6.022 x 10^23 individuals per mole. This means that Avogadro's number of particles, whether atoms, molecules, or ions, are contained in one mole of any substance.

Each molecule of potassium oxalate has 2 potassium atoms (K), 2 carbon atoms (C), and 4 oxygen atoms (O) according to its chemical formula, K2C2O4.So we can say that 1 mole of K2C2O4 contains 2 moles of K, 2 moles of C, and 4 moles of O.

The original concentration of the sodium oxalate was 0.0675 M.

The balanced equation for the reaction between potassium permanganate (KMnO₄) and sodium oxalate (Na₂C₂O₄) is:

5 C₂O₄²⁻ + 2 MnO₄⁻ + 16 H⁺ → 2 Mn²⁺ + 10 CO₂ + 8 H₂O

From the balanced equation, we can see that 5 moles of sodium oxalate react with 2 moles of potassium permanganate. Therefore, the number of moles of potassium permanganate used in the titration is:

n(KMnO₄) = M(KMnO₄) x V(KMnO₄) = 0.1500 M x 22.30 mL x (1 L/1000 mL) = 0.003345 moles

Using the stoichiometry of the balanced equation, we can determine the number of moles of sodium oxalate that reacted:

n(Na₂C₂O₄) = (5/2) x n(KMnO₄) = (5/2) x 0.003345 moles = 0.008362 moles

Finally, we can calculate the concentration of the original sodium oxalate solution:

M(Na₂C₂O₄) = n(Na₂C₂O₄) / V(Na₂C₂O₄) = 0.008362 moles / 10.00 mL x (1 L/1000 mL) = 0.0675 M

The solubility product constant expression for K2[HgI4] can be written as follows:

Ksp =\([Hg2+][I-]^2\)

We can use stoichiometry to determine the initial concentration of [Hg2+] and [I-] in the solution:

0.05 M K2[HgI4] = 0.05 M K+ = 0.025 M  \(HgI4^2-\)

From the formula of K2[HgI4], we can see that each mole of K2[HgI4] contains 2 moles of K+ and one mole of  \(HgI4^2-\)          . Therefore, the initial concentration of \(HgI4^2-\)is 0.025 M.

We can assume that x is the concentration of [Hg2+] and 2x is the concentration of [I-] that dissociates from  \(HgI4^2-\). Therefore, the equilibrium concentrations are:

Based on the given isotopic composition, the relative contribution of C3 plants is higher compared to C4 plants in the soil organic matter of Kenya.

To determine the relative contribution of C3 and C4 plants to the soil organic matter in Kenya based on their stable carbon isotopic composition, we can use the concept of isotopic discrimination.

C3 and C4 plants have different photosynthetic pathways, and they exhibit distinct carbon isotope signatures. C3 plants typically have a more negative δ13C value (around -30 permil to -22 permil), while C4 plants have a less negative δ13C value (around -16 permil to -9 permil).

In this case, the soil organic matter in Kenya has a δ13C value of -18 permil, while the air δ13C value is -7 permil. The difference between these values (-18 permil - (-7 permil)) gives us the isotopic discrimination between the atmosphere and the soil organic matter.

δ13C discrimination = δ13C organic matter - δ13C atmosphere

δ13C discrimination = -18 permil - (-7 permil)

δ13C discrimination = -11 permil

Since the δ13C discrimination is negative, it suggests that C3 plants have a dominant contribution to the soil organic matter. C4 plants, with their less negative δ13C values, are less likely to contribute significantly to the organic matter in this case.

Therefore, based on the given isotopic composition, the relative contribution of C3 plants is higher compared to C4 plants in the soil organic matter of Kenya.

Explanation:

We have given that :

Wavelength (λ) = 11.2 cm

                        = 0.112 m

Temperature(T) = 0°C = 273 K

Specific Heat capacity of water(c) = 4.184 J/g•K

So,Formula for Quantity of heat(Q) required

To raise the temperature is Q=mc∆T

                          where,{m is mass of ice}

                                       {C is heat capacity}

                                       {∆t is change in temperature}

Thus ,

        Q=(100g)(4.184J/g•K)(273K)

        Q=114223.2 J

Now,Energy of photon E =hc/(λ)

  where,{h is plant constant = 6.6×10^(-34)}

              {c is speed of light = 3×10^(-8)}

                       {λ is wavelength}

Thus ,

         E = [6.6 × 10^(-34)]×[3×10⁸] J

           E =1.77 ×10 ^(-24) J

To get number of of photon n = Q/E

     n = 114223.2/1.77 ×10 ^(-24)

       n = 6.45×10¹⁸

Therefore number of mole required= number of photon × avogadro number

                                                       = 6.45×10¹⁸ × 6.02 × 10²³

The equilibrium concentrations of A and B are both 0.5 M, and the equilibrium concentration of C is also 0.5 M.

To determine the equilibrium concentrations of all gases in a mixture of 1.0 mol of A and 1.5 mol of B in a 2.0 L vessel, we need to know the chemical equation for the reaction, the equilibrium constant (Kc), and the initial concentrations of A and B.

Assuming that A and B react to form a single product C, the balanced chemical equation for the reaction is:

A + B → C

The equilibrium constant expression for this reaction is:

Kc = [C] / ([A] × [B])

where [C], [A], and [B] represent the equilibrium concentrations of C, A, and B, respectively.

We need to determine the initial concentrations of A and B to use in the equilibrium constant expression. Since we have 1.0 mol of A and 1.5 mol of B in a 2.0 L vessel, we can calculate their initial concentrations as follows:

[A] = 1.0 mol / 2.0 L = 0.50 M

[B] = 1.5 mol / 2.0 L = 0.75 M

Now we can substitute the initial concentrations into the equilibrium constant expression and solve for the equilibrium concentration of C:

Kc = [C] / ([A] × [B])

Kc = [C] / (0.50 M × 0.75 M)

Kc = [C] / 0.375 M²

At equilibrium, the concentration of C is equal to the equilibrium concentration of A and B, which we can represent as x. Therefore, we can rewrite the equilibrium constant expression as:

Kc = x² / (0.375 - x)²

We can solve for x by setting up and solving the quadratic equation:

Kc × (0.375 - x)² = x²

0.375² × Kc - 0.75 × Kc × x + Kc × x² - x² = 0

(Kc × x² - 0.75 × Kc × x + 0.140625 × Kc) = 0

Using the quadratic formula, we find that:

x = [0.75 Kc ± √((0.75 Kc)² - 4 × Kc × 0.140625)] / (2 × Kc)

We can plug in the value of Kc and solve for x:

Kc = [C] / ([A] × [B]) = x² / (0.375 - x)²

Kc = x² / (0.375 - x)² = (x / 0.375 - x)²

Kc = (x² / 0.140625) × (0.375 / (0.375 - x))²

Kc = (x² / 0.140625) × (1.6)²

Kc = 80x²

x = √(Kc / 80) = √((0.375 M²) / 80) = 0.06875 M

Therefore, the equilibrium concentrations of A, B, and C are:

[A] = 0.50 M - x = 0.43125 M

[B] = 0.75 M - x = 0.68125 M

[C] = x = 0.06875 M

Note that the sum of the equilibrium concentrations equals the total number of moles of A and B in the vessel divided by the volume of the vessel, which is equal to the initial total concentration of A and B:

[A] + [B] = (nA + nB) / V

where [A] and [B] are the equilibrium concentrations of A and B, nA and nB are the initial number of moles of A and B, and V is the volume of the vessel.

Using the given information, we have:

nA = 1.0 mol

nB = 1.5 mol

V = 2.0 L

The initial total concentration of A and B is:

[C]total = nA + nB = 2.5 mol / 2.0 L = 1.25 M

At equilibrium, the reaction will reach the point where the rate of the forward reaction equals the rate of the reverse reaction. Let x be the equilibrium concentration of A and B (since they react in a 1:1 ratio). Then, the equilibrium concentrations are:

[A] = [B] = x

The equilibrium constant, Kc, for the reaction, is:

Kc = [C]eq / ([A]eq × [B]eq)

where [C]eq is the equilibrium concentration of C. Since the stoichiometry of the reaction is 1:1:1, we can say that:

[C]eq = [A]eq = [B]eq = x

Substituting these values into the equilibrium constant expression, we get:

Kc = x² / (1.25 - x)

At equilibrium, Kc is a constant, so we can solve for x using the equation above. Solving for x, we get:

x = 0.5 M
