Chapter 18, Problem 18.62QP

Interpretation Introduction

Interpretation: A gas phase reaction mixture is given to have a one mole of reactant and product and stoichiometry of $1:1$. The explanation of the statement that $\Delta G_{\text{rxn}}^{\text{ο}}$ is same as $\Delta H_{\text{rxn}}^{\text{ο}}$ is to be stated.

Concept introduction: The $\Delta G_{\text{rxn}}^{\text{ο}}$ of a reaction is calculated by the formula,

$\Delta G_{\text{rxn}}^{\text{ο}}=\Delta H_{\text{rxn}}^{\text{ο}}-T\Delta S_{\text{rxn}}^{\text{ο}}$

To determine: The explanation of the statement that $\Delta G_{\text{rxn}}^{\text{ο}}$ is same as $\Delta H_{\text{rxn}}^{\text{ο}}$.
