Given the standard potential for the following half-cell reaction at 298 K
\[ \begin{array}{ll} \mathrm{Cu}^{+}(\mathrm{aq})+\mathrm{e}^{-} \rightarrow \mathrm{Cu(s)} & \mathrm{E}_{0}=0.52\,\mathrm{V} \\ \mathrm{Cu}^{2+}(\mathrm{aq})+\mathrm{e}^{-} \rightarrow \mathrm{Cu}^{+}(\mathrm{aq}) & \mathrm{E}_{0}=0.16\,\mathrm{V} \end{array} \]
Calculate the $\Delta \mathrm{G}^{0}(\mathrm{kJ})$ for the reaction, $2\mathrm{Cu}^{+}(\mathrm{aq}) \rightarrow \mathrm{Cu}^{+}(\mathrm{s})+\mathrm{Cu}^{2+}$
