\( \mathrm{Cu}^{+} \)(aq) is unstable in solution and undergoes simultaneous oxidation and reduction according to the reaction.
\[2 \mathrm{Cu}^{+}{ }_{(\mathrm{aq})} \longrightarrow \mathrm{Cu}^{2+}{ }_{(\mathrm{aq})}+\mathrm{Cu}_{(\mathrm{s})}\]
Choose correct \( \mathrm{E}^{0} \) for the above reaction if \( \mathrm{E}_{\mathrm{Cu}^{2+} / \mathrm{Cu}}^{0}=0.34 \mathrm{~V} \) and \( \mathrm{E}_{\mathrm{Cu}^{2+} / \mathrm{Cu}^{+}}^{0}=0.15 \mathrm{~V} \)
