Predict whether the ∆S° for the given reaction is expected to be less than, greater than, or equal to 0. Explain.

The hydrogenation of 2-butene to produce butane is shown below:

In terms of entropy, is the reaction favored or disfavored?

Provide the temperature at which any value of the entropy change of a process becomes negligible in determining its spontaneity.

In the given reaction, if the temperature is increased, which side of the reaction, if any, would be favored?

A reaction with an equilibrium constant of 2.00 × 10^–5 is conducted at 25°C. To increase the equilibrium constant by a factor of 100, what is the required change in each of the following?

(i) ΔG°

(ii) ΔH°, if ΔS° = 0

(iii) ΔS°, if ΔH° = 0

The rate constants of a certain reaction at different temperatures were recorded as shown below.

Calculate the activation energy, ΔG^‡, ΔH^‡, ΔS^‡ of the reaction at 50°C. Express your answers to three significant figures.
