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) $-375.060\text{ kJ mol}^{-1}$
