Chapter 17, Problem 67E

A galvanic cell is based on the following half-reactions at 25°C:

${\text{Ag}}^{+}+{\text{ e}}^{-}\to \text{ Ag}$

${\text{H}}_{\text{2}}{\text{O}}_2+{\text{ 2H}}^{+}+{\text{ 2e}}^{-}\to 2{\text{H}}_{\text{2}}\text{O}$

Predict whether  is larger or smaller than  for the following cases.

a. $\left[{\text{Ag}}^{+}\right]=1.0M,[{\text{H}}_{\text{2}}{\text{O}}_{\text{2}}]=2.0M,\left[{\text{H}}^{\text{+}}\right]=2.0M$

b. $\left[{\text{Ag}}^{+}\right]=\text{ 2}.0M,[{\text{H}}_{\text{2}}{\text{O}}_{\text{2}}]=\text{ 1}.0M,\left[{\text{H}}^{\text{+}}\right]=\text{ 1}\text{.0}\times {\text{10}}^{-7}M$
