Chapter 19, Problem 11PE

Interpretation Introduction

Interpretation:

Under standard state conditions, each of the given equations are to be written such that they represent spontaneous reactions.

Concept Introduction:

The standard reduction potential of a galvanic cell may be calculated from the standard reduction potentials as mentioned below:

$E_{\text{cell}}^{\text{o}}=E_{\text{reduction}}^{\text{o}}-E_{\text{oxidation}}^{\text{o}}$.

The reaction is spontaneous, if the standard cell potential is positive. The reverse reaction is spontaneous if the standard cell potential is negative.
