Chapter 6, Problem 6C.5BE

Interpretation Introduction

Interpretation: The factor by the cell potential change when $Q$ is increased by the factor of $5$ for a reaction at the given conditions.

Concept introduction: Nernst equation is the relation between standard electrode potential and the electrode potential at given conditions of pressures, temperatures and concentrations.  The expression for Nernst equation is,

    $E_{\text{cell}}=E_{\text{cell}}^{\text{ο}}-\frac{RT}{vF}\ln Q$

Where,

• $E_{\text{cell}}$ is the electrode potential of the cell.
• $E_{\text{cell}}^{\text{ο}}$ is the standard electrode potential of the cell.
• $R$ is the gas constant.
• $T$ is the temperature.
• $v$ is the number of electrons.
• $F$ is the Faraday’s constant.
• $Q$ is the reaction quotient.
