Chapter 23, Problem 23.24P

Interpretation Introduction

Interpretation:

Value of ${\text{ΔG}}_{\text{rxn}}$ has to be calculated for the reaction ${\text{2 SO}}_2\left(\text{g}\right){\text{ + O}}_2\left(\text{g}\right)\stackrel{}{\to }2{\text{SO}}_{\text{3}}\left(\text{g}\right)$.

Concept Introduction:

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by $\text{ΔG}$. The formula of ${\text{ΔG}}_{\text{rxn}}$ at thermodynamic equilibrium,

    ${\text{ΔG}}_{rxn}=\text{RT}\text{ln}\left(\frac{\text{Q}}{K}\right)$
