Chapter 9, Problem 9.26A

Interpretation Introduction

Interpretation:

The temperature at which the reaction is at equilibrium needs to be determined. Whether the temperature is increased or decreased to make the reaction spontaneous needs to be explained.

Concept introduction:

The relation between change in enthalpy, change in Gibbs free energy and change in entropy is represented as follows:

$\Delta G^{\text{o}}=\Delta H^{\text{o}}-T\Delta S^{\text{o}}$

Here, $\Delta G^{\text{o}}$ is change in Gibbs free energy, $\Delta H^{\text{o}}$ is change in enthalpy, T is temperature and $\Delta S^{\text{o}}$ is change in entropy.
