Chapter 17, Problem 17.9P

Interpretation Introduction

Interpretation:

The free energy of the given reaction is to be calculated using the partial pressures of the reactant and the product and the spontaneity of the reaction is to be compared with that under the standard condition.

Concept introduction: The free energy, $\Delta G$ , of the reaction is calculated as,

$\Delta G=\Delta G°-\text{Absolute}\text{temperature}\times \text{Gas}\text{constant}\times \ln \frac{\text{Partial}\text{pressure}\text{of}\text{product}}{\text{Partial}\text{pressure}\text{of}\text{reactant}}$

If $\Delta G$ is less negative than $\Delta G°$ , the reaction is less spontaneous than that under standard condition.

To determine: The free energy of the given reaction and the comparison of the spontaneity of the reaction with that under the standard condition.
