Chapter 19, Problem 19.31P

Interpretation Introduction

Interpretation:

The Gibbs free energy, standard cell potential and the equilibrium constant for the given cell reaction are to be determined.

Concept introduction:

The change in the free energy for a given reaction can be defined as a measure of the maximum amount of work which can be done during a chemical reaction or a process. The relation between the cell potential and the Gibbs free energy is as follows:

${\text{ΔG}}^{\text{o}}{\text{=-nFE}}_{\text{cell}}^{\text{o}}$

Here, n is the number of electron/s transferred in the reaction, F is Faraday’s constant and ${\text{E}}_{\text{cell}}^{\text{o}}$ is electrode potential of the cell.
