From the following half-cell reactions:
\( \text{Zn}^{2+} + 2e^- \rightarrow \text{Zn}(s); \, E^\circ = -0.76 \, \text{V} \)
\( \text{Cu}^+ + e^- \rightarrow \text{Cu}(s) + \text{I}^-(aq); \, E^\circ = +0.17 \, \text{V} \)
The standard potential \( E^\circ \) of the cell
\( \text{Zn, Zn}^{2+}(1 \, \text{M}) \, \text{—} \, \text{I}^-(1 \, \text{M}), \text{Cu}^+; \, \text{Cu} \) will be:
