The major organic product for the given two step reaction is lithium diisopropyl amide (LDA).

The chemical molecule known as lithium diisopropyl amide, or LDA for short, has the molecular formula LiN(CH(CH₃)₂)₂. Due to its non-nucleophilic character as well as excellent solubility in non-polar organic solvents, it is a strong base that is frequently used. It is a colorless solid which is often only produced and seen in the solutions.

LDA is strongly polar yet, like the majority of organolithium reagents, is not a salt. In solution, it aggregates, to varying degrees depending on the solvent's properties. Its structure in THF is essentially that of a dimer that has been solvated. While LDA in its solid form is pyrophoric, its solutions are typically not. As a result, it is readily accessible in the market as a solution in polar aprotic solvents like THF and ether; but, for small-scale applications (less than 50 mmol), it is more usual and financially advantageous to manufacture LDA in situ.

Sublimation is the process by which a substance moves straight from the solid phase to the gas phase without first going through the liquid phase (Table 4.8, Fig. 4.2). At temperatures and pressures lower than a chemical's triple point in the phase diagram, sublimation, an endothermic phase transition, takes place. a method by which a substance transforms from a liquid to a solid. When the temperature drops low enough, everything except helium begins to freeze. A substance turns from a liquid to a solid through the process of freezing. When a liquid's molecules slow down enough to attract one another and organize themselves into stable places as a solid, freezing happens.

If the zero is located in the RHP and the poles are located in the LHP, it is possible that the process will exhibit an inverse response based on the transfer function G(s) = K(Tzs + 1) / ((115 + 1)(T25 + 1)).

To determine when the process will possess an inverse response based on the given transfer function G(s) = K(Tzs + 1) / ((115 + 1)(T25 + 1)), we need to analyze the characteristics of the transfer function.

In a transfer function, an inverse response occurs when the sign of the phase angle changes by 180 degrees or π radians as the frequency increases. Mathematically, this corresponds to a pole and a zero that are located in the right-half plane (RHP) of the complex plane.

From the given transfer function G(s) = K(Tzs + 1) / ((115 + 1)(T25 + 1)), we can observe the following:

The numerator of the transfer function has a single zero, which is given by (Tzs + 1).

The denominator of the transfer function has two poles, which are given by ((115 + 1)(T25 + 1)).

To determine the location of the poles and zeros, we need specific values for T, z, and K. Without those values, we cannot determine the exact location of the poles and zeros or whether they lie in the RHP.

However, in general, if the zero (Tzs + 1) is located in the RHP and the poles ((115 + 1)(T25 + 1)) are located in the left-half plane (LHP), the transfer function may possess an inverse response. The presence of a pole in the RHP and a zero in the LHP can lead to an inverse response behavior.

The value of activation energy for the reaction in kJ/mol is obtained by using the Arrhenius equation.

Activation energy is represented by E_a, the frequency factor is represented by A, the gas constant is represented by R, the temperature is represented by T, and the rate constant is represented by k.

According to the Arrhenius equation

ln k = (- E_a/ R) + ln

Taking the exponential A of both sides

k = Ae^(-Ea/RT)k = A × e^(-Ea/RT)

Taking natural logarithms on both sides, we obtain;

ln k = ln A + (-Ea/RT)

If we consider a plot of ln k vs. 1/T, the equation becomes

y = mx + Cln k = (-Ea/R) (1/T) + ln A

From this equation, we can see that the slope of the best-fit line is -Ea/R.

Therefore, by using the slope value of the best-fit line as -2475 k, the activation energy is obtained by rearranging the above equation as; Ea = -slope x R= (-2475 k) × (8.314 J mol^−1 K^−1)≈ 20.5 kJ/mol

Therefore, the value of the activation energy for the reaction in kj/mol is approximately equal to 20.5 kJ/mol.

Given that the initial concentration of HZ is 5.0 moles and at equilibrium, 8.7% of the acid has become hydronium.

The concentration of HZ that has not reacted is (100% - 8.7%) = 91.3%.

The final concentration of HZ is 5.0 × 0.913 = 4.565 moles.

The final concentration of the hydronium ion is 5.0 × 0.087 = 0.435 M.HZ ⇌ H+ + Z-Ka

= [H+][Z]/[HZ]Ka

= [H+][Z]/[HZ]

= [0.435]² / 4.565

= 0.041

Which is the same as 4.1 × 10-3.

We know that HZ is an acid that will partially ionize in water to give H+ and Z-.

The chemical equation for this reaction can be written as HZ ⇌ H+ + Z-.

The acid dissociation constant (Ka) of HZ is the equilibrium constant for the reaction in which HZ ionizes to form H+ and Z-.Thus, Ka = [H+][Z]/[HZ].

The given problem is a typical example of the dissociation of a weak acid in water. We are given the initial concentration of HZ and the concentration of hydronium ions at equilibrium.

To find the equilibrium concentration of HZ, we can use the fact that the total amount of acid is conserved.

At equilibrium, 8.7% of HZ has dissociated to give hydronium ions.

This means that 91.3% of the original HZ remains unreacted.

Therefore, the concentration of HZ at equilibrium is 5.0 × 0.913 = 4.565 M.

The concentration of hydronium ions at equilibrium is 5.0 × 0.087 = 0.435 M.

Using the equation Ka = [H+][Z]/[HZ], we can substitute the values of the concentrations and the equilibrium constant into the equation and solve for Ka.

Ka = [H+][Z]/[HZ]

= [0.435]² / 4.565
