For a cell, $\displaystyle \mathrm{Cu}(\mathrm{s})\left|\mathrm{Cu}^{2+}(0.001 \mathrm{M}) \| \mathrm{Ag}^{+}(0.01 \mathrm{M})\right| \mathrm{Ag}(\mathrm{s})$ the cell potential is found to be $\displaystyle 0.43$ V at $\displaystyle 298$ K. The magnitude of standard electrode potential for $\displaystyle \mathrm{Cu}^{2+} / \mathrm{Cu}$ is \_\_\_\_ $\displaystyle \times 10^{-2} \mathrm{~V}$. $$\left[\text { Given : } \mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{\ominus}=0.80 \mathrm{~V} \text { and } \frac{2.303 \mathrm{RT}}{\mathrm{~F}}=0.06 \mathrm{~V}\right] $$
