Chapter 22, Problem 22.82P

Interpretation Introduction

Interpretation:

The free energy change for splitting hydrogen sulphide with that for splitting water has to be compared.  Also, using hydrogen sulfide instead of water gives advantage or not has to be provided.

Concept Introduction: 

Free energy, ${\text{ΔG}}^{\text{ο}}$, is the measure of the ability of a reaction to proceed spontaneously. ${\text{ΔG}}^{\text{ο}}$ can be calculated with the relationship.

    ${\displaystyle \sum _{}^{}{\text{mΔG}}_{{}^{\text{f}}\text{(products)}}^{\text{o}}\text{-}}{\displaystyle \sum _{}^{}{\text{mΔG}}_{{}^{\text{f}}\text{(reactants)}}^{\text{o}}}$
