Chapter 11, Problem 45E

Interpretation Introduction

Interpretation: The given equations need to be combined to drive an expression for ${\text{E}}^{\text{0}}$ as a function of temperature.

Concept introduction: Cell potential I defined as the maximum electrical work that can be obtained from the electrochemical cell which is given by the $\Delta \text{G}$ (Gibbs Free Energy)

The relation is given as:

  $\text{ΔG}\text{=}-{\text{nFE}}^{\text{0}}{}_{\text{cell}}$

More the cell potential, more negative is the $\text{ΔG}$ of a system.

Process is spontaneous if ${\text{E}}^{\text{0}}{}_{\text{cell}}>0$

Process is non-spontaneous if ${\text{E}}^{\text{0}}{}_{\text{cell}}<0$
