Chapter 8, Problem 8.23E

Interpretation Introduction

Interpretation:

The value of $E°$ for the given reaction is to be calculated.

Concept introduction:

Standard Gibbs free energy of a reaction is the calculated by subtracting the standard Gibbs free energy of formation of reactants from standard Gibbs free energy of formation of products. The formula for standard Gibbs free energy of reaction is given as,

${\Delta }_{\text{rxn}}G°={\displaystyle \sum {\Delta }_{\text{f}}G°\left(\text{products}\right)}-{\displaystyle \sum {\Delta }_{\text{f}}G°\left(\text{reactants}\right)}$

Where,

• ${\Delta }_{\text{f}}G°\left(\text{products}\right)$ represents the standard Gibbs free energy of formation of products.

• ${\Delta }_{\text{f}}G°\left(\text{reactants}\right)$ represents the standard Gibbs free energy of formation of reactants.
