Chapter 18, Problem 82AP

Interpretation Introduction

Interpretation:

The pressure of ${\text{O}}_2$ is to be calculated.

Concept introduction:

The standard Gibbs free energy is calculated by using the expression as follows:

$\Delta G_{}^{\text{o}}=-RT\ln {\text{K}}_{\text{p}}\text{.}$ …… (1)

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