Chapter 23, Problem 13QP

Interpretation Introduction

Interpretation:

The equilibrium constant for the given reaction at a temperature of ${80}^{\text{o}}\text{C}$ is to be calculated.

Concept introduction:

The standard free energy change of a reaction is equal to the difference between the Gibbs free energies of the products and the reactants.

The relation between $\Delta G^{\text{o}}$ and $K_{\text{p}}$ is represented as follows:

$\Delta G^{\text{o}}=-RT\ln K_{\text{P}}$

Here, $\Delta G^{\text{o}}$ is the standard free energy change, $R$ is the universal gas constant, $T$ is the temperature, and $K_{\text{P}}$ is the equilibrium constant.
