Standard electrode potential for
\( \begin{array}{l} \mathrm{Cu}^{+2}+\mathrm{e}^{-} \rightarrow \mathrm{Cu}^{+} \\ \mathrm{Cu}^{+}+\mathrm{e}^{-} \rightarrow \mathrm{Cu} \end{array} \)
are \( 0.15 \mathrm{~V} \) and \( 0.50 \mathrm{~V} \) respectively.
The value of \( \mathrm{E}_{\mathrm{Cu}^{+2} / \mathrm{Cu}}^{0} \) will be
