Electrochemistry

A reaction, \(\mathrm{Ni}_{(\mathrm{s})}+\mathrm{Cu}_{(\mathrm{(M)})}^{+} \rightarrow \mathrm{Ni}_{(\mathrm{IM})}^{+}+\mathrm{Cu}_{(\mathrm{s})}\) occurs in a cell. Calculate \(\mathrm{E}_{\text {cell }}^{\circ}\) if \(\mathrm{E}_{\mathrm{Cu}}^{\circ}=0.337 \mathrm{~V}\) and \(\mathrm{E}_{\mathrm{Ni}}^{\circ}=-0.257 \mathrm{~V}\)
