Q.
Given the standard potential for the following half-cell reaction at 298 K,
$Cu^{+}\left(a q\right)+e^{-} \rightarrow Cu\left(s\right);$ $E^\circ =0.52V$
$Cu^{2 +}\left(a q\right)+e^{-} \rightarrow Cu^{+}\left(a q\right);$ $E^\circ =0.16V$
Calculate the $\Delta G^\circ $ (kJ) for the reaction, $\left[2 C u^{+} \left(a q\right) \rightarrow C u \left(s\right) + C u^{2 +}\right]$
