The standard free energy of the reaction
\[ \mathrm{AgBr}(\mathrm{s}) \rightarrow \mathrm{Ag}^{+}(\mathrm{aq})+\mathrm{Br}^{-}(\mathrm{aq}) \]
Is closest to.
\[ \left[\mathrm{E}^{\circ}\left(\mathrm{AgBr} / \mathrm{Ag}, \mathrm{Br}^{-}\right)=0.07 \mathrm{V} ; \mathrm{E}^{\circ}\left(\mathrm{Ag} / \mathrm{Ag}^{+}\right)=0.80 \mathrm{V} ; \mathrm{F}=96500 \mathrm{C} \mathrm{mol}^{-1}\right] \]
(a)$7 \mathrm{kJ} \mathrm{mol}^{-1}$
