Chapter 14, Problem 14.47P

(a)

Interpretation Introduction

Interpretation:

Nernst equation for given reaction has to be written.

Concept introduction:

Nernst equation is,

${\text{E = E}}_{\text{o}}\text{-}\frac{0.05916}{\text{n}}\text{ln}\text{Q}$

Where,

$\begin{array}{l}{\text{E}}_{\text{o}}\text{-Standardpotentialofthecell}\\ \\ \text{n - Number of electrons}\\ \\ \text{Q - Reactant quotient}\end{array}$

(b)

Interpretation Introduction

Interpretation:

Given Nernst equation has to be rearranged.

(c)

Interpretation Introduction

Interpretation:

For $\text{pH}$ is 7, ${\text{E}}^{\text{o'}}$ has to be evaluated.
