Chapter ER, Problem 29PQ

Interpretation Introduction

Interpretation:

The true statement which is appropriate for the given reaction has to be given.

Concept Introduction:

The Nernst equation is,

  ${\text{E}}_{\left(\text{cell}\right)}{\text{=E}}^{\text{o}}{}_{\left(\text{cell}\right)}\text{-}\frac{\text{RT}}{\text{nF}}\text{lnQ}$

Where,

• ${\text{E}}_{\left(\text{cell}\right)}$ is the reduction potential at the current conditions.
• ${\text{E}}^{\text{o}}{}_{\left(\text{cell}\right)}$ is the standard reduction potential relative to hydrogen  reduction potential at ${\text{25}}^{\text{o}}\text{C}\text{.}$
• $\text{R}$ is the universal gas constant.
• $\text{T}$ is the temperature in $\text{K}$
• n is the moles of electrons transferred between the positive and negative terminals of the electrochemical system.
• $\text{F}$ is Faraday's constant.
• $\text{Q}$ is the Reaction Quotient.
