\text{Cu}^+ + \text{e}^- \rightarrow \text{Cu}

E^{\circ} = x_1\ \text{volt}

;

\text{Cu}^{2+} + 2\text{e}^- \rightarrow \text{Cu}

E^{\circ} = x_2\ \text{volt}

, then for

\text{Cu}^{2+} + \text{e}^- \rightarrow \text{Cu}^+

E^{\circ}

(volt) will be: (a)

x_1 - 2x_2

(b)

x_1 + 2x_2

(c)

x_1 - x_2

(d)

2x_2 - x_1
