Chapter 18, Problem 102AP

Interpretation Introduction

Interpretation:

The equilibrium constantfor the given reactionis to be calculated.

Concept introduction:

The equilibrium constant is calculated by using the expression given as follows:

$\Delta G_{}^o=-RT\ln K_p$

Here, $\text{R}$ is the universal gas constant, $T$ is the absolute temperature, $K_p$ is the equilibrium pressure constant, and $\Delta G^o$ is the Gibbs free energy change.

The reaction is spontaneous if $\Delta G^{\circ }$ is negative.
