Consider the following reaction :
$\text{Zn}_{(s)} + \text{Ag}_2\text{O}_{(s)} + \text{H}_2\text{O}(l) \rightarrow \text{Zn}^{2+}_{(aq)} + 2\text{Ag}_{(s)} + 2\text{OH}^-_{(aq)}$
Given : $E^\circ_{\text{Ag}^+/\text{Ag}} = 0.80\text{ V}$
$E^\circ_{\text{Zn}^{2+}/\text{Zn}} = -0.76\text{ V}$
$1\text{ F} = 96500\text{ C mol}^{-1}$
$\Delta_r G^\circ$ for the above reaction is :
(A) $-301.080\text{ kJ mol}^{-1}$
(B) $+310.080\text{ kJ mol}^{-1}$
(C) $-326.070\text{ kJ mol}^{-1}$
(D) $-375.060\text{ kJ mol}^{-1}$
