Chapter 5, Problem 5I.5ST

Interpretation Introduction

Interpretation:

For the given nickel-cadmium electrode, reaction Gibbs energy has to be calculated.

Concept Introduction:

Gibbs energy and Cell potential:

The relationship between Gibbs energy and the cell potential is given by,

$\begin{array}{l}{\text{-vFE}}_{\text{Cell}}\text{=}{\text{Δ}}_{\text{r}}\text{G}\\ \text{where,}\\ \text{v}\text{-}\text{number of electrons transferred}\text{in the cell reaction}\\ \text{F}\text{-}\text{Faraday's}\text{constant}\\ {\text{E}}_{\text{cell}}\text{-}\text{cell}\text{potential}\text{and}{\text{Δ}}_{\text{r}}\text{G}\text{-}\text{reaction}\text{Gibbs}\text{energy}\end{array}$
