Chapter 18, Problem 37E

Interpretation Introduction

Interpretation:

Thecell potentials $\left(E_{\text{cell}}\right)$ of the givenredox reactions at $25°\text{C}$ under given conditions are to be calculated.

Concept introduction:The cell potential $\left(E_{\text{cell}}^{\text{ο}}\right)$ of given balanced reaction at standard condition is calculated by the formula,

$E_{\text{cell}}^{\text{ο}}=E_{\text{cathode}}^{\text{ο}}-E_{\text{anode}}^{\text{ο}}$

The cell potential $\left(E_{\text{cell}}\right)$ of a given balanced reaction at non-standard condition is calculated by the Nernst formula,

$E_{\text{cell}}=E_{\text{cell}}^{\text{ο}}-\frac{0.0592\text{V}}{n}\log \frac{\left[\text{Anode}\right]}{\left[\text{Cathode}\right]}$

To determine:Thecell potentials $\left(E_{\text{cell}}\right)$ of the given reactions at $25°\text{C}$ under given conditions.
