Chapter 19, Problem 71AP

From the following information, calculate the solubility product of $\text{AgBr:}$

$\begin{array}{l}{\text{Ag}}^{\text{+}}(aq)+e^{-}\underset{}{\to }\text{Ag}(s)E°\text{ = 0}\text{.80 V}\\ \text{AgBr}(s)+e^{-}\underset{}{\to }\text{Ag}(s)+{\text{Br}}^{\text{-}}(aq)E°\text{ = 0}\text{.07 V}\end{array}$
