In an electrolytic cell,the flow of electrons is from:

$A$ solution of copper sulphate may be kept safely in the container made up of

The zinc/silver oxide cell is used in electric watches. The reaction is as follows:
$Zn(s) + Ag_2O(s) + H_2O(l) \rightarrow Zn^{2+}(aq) + 2Ag(s) + 2OH^-(aq)$
Given:
$Zn^{2+} + 2e^- \rightarrow Zn ; E^{\circ} = -0.760 \, V$
$Ag_2O + H_2O + 2e^- \rightarrow 2Ag + 2OH^- ; E^{\circ} = 0.344 \, V$
If $F = 96,500 \, C \, mol^{-1}$,the $\Delta G^{\circ}$ of the cell will be $....$ (in $kJ \, mol^{-1}$)
