The standard free energy of the reaction
$\mathrm{AgBr}(\mathrm{s}) \rightarrow \mathrm{Ag}^{+}(\mathrm{aq}) + \mathrm{Br}^{-}(\mathrm{aq})$
Is closest to. $[\mathrm{E}^{\circ}(\mathrm{AgBr}/\mathrm{Ag},\mathrm{Br}^{-}) = 0.07\,\mathrm{V}\ ;\ \mathrm{E}^{\circ}(\mathrm{Ag}/\mathrm{Ag}^{+}) = 0.80\,\mathrm{V};\ \mathrm{F} = 96500\,\mathrm{C}\,\mathrm{mol}^{-1}]$
(a)$7\,\mathrm{kJ}\,\mathrm{mol}^{-1}$
(b)$70\,\mathrm{J}\,\mathrm{mol}^{-1}$
