Chapter 22, Problem 22.63P

(a)

Interpretation Introduction

Interpretation:

The overall balanced equation for the given process has to be written.

Concept Introduction:

Balanced Chemical equation:

A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.

(b)

Interpretation Introduction

Interpretation:

The possibility of oxidation of hydrogen sulfide by chlorine using thermodynamic data has to be predicted.

Concept Introduction:

The change in standard Gibbs free energy is given by,

    ${\text{ΔG}}^{\text{o}}{}_{\text{rxn}}\text{=}{\displaystyle \sum _{}^{}\text{m}}{\text{ΔG}}_{\text{f}}{{}^{\text{o}}}_{\text{(products)}}\text{-}{\displaystyle \sum _{}^{}\text{n}}{\text{ΔG}}_{\text{f}}{{}^{\text{o}}}_{\text{(reactants)}}$

(c)

Interpretation Introduction

Interpretation:

The preference of oxygen over chlorine for oxidation of hydrogen sulfide has to be explained.
