Under which of the following conditions \(E\) value of the cell, for the cell reaction given is maximum?
\(\mathrm{Zn}(s)+\mathrm{Cu}^{2+}(a q) \rightleftharpoons \mathrm{Cu}(s)+\mathrm{Zn}^{2+}(a q)\)
\(\left(\begin{array}{l}
\frac{2.303 R T}{F} \text { at } 298 \mathrm{~K}=0.059 \mathrm{~V}, \\
E_{\mathrm{Zn}^{2+} / \mathrm{Zn}}^{\circ}=-0.76 \mathrm{~V}, E_{\mathrm{Cu}^{2^{+}} / \mathrm{Cu}}^0=+0.34 \mathrm{~V}
\end{array}\right)\)
