Chapter 5, Problem 5I.6ST

Interpretation Introduction

Interpretation:

The increase in cell potential has to be calculated when the value of Q is increased by a factor of 20.

Concept Introduction:

Nernst equation:

The relationship between cell potential and the composition of the reaction mixture is given by,

$\begin{array}{l}{\text{E}}_{\text{Cell}}\text{=}{\text{E}}^{\text{o}}{}_{\text{Cell}}\text{-}\frac{\text{R}\text{T}}{\text{vF}}\text{ln}\text{Q}\\ \text{where,}\\ {\text{E}}_{\text{Cell}}\text{-}\text{cell potential}\\ {\text{E}}^{\text{o}}{}_{\text{Cell}}\text{-}\text{standard}\text{cell potential}\\ \text{F}\text{-}\text{Faraday's}\text{constant}\\ \text{Q}\text{-}\text{reaction}\text{quotient}\\ \text{v}\text{-}\text{number}\text{of}\text{electrons}\text{transfered}\\ \text{R}\text{-}\text{gas}\text{constant}\text{and}\text{T}\text{-}\text{temperature}\end{array}$
