The standard EMF for the cell reaction, $\mathrm{Zn}+\mathrm{Cu}^{2+} \longrightarrow \mathrm{Cu}+\mathrm{Zn}^{2+}$ is1.1 volt at $25^{\circ} \mathrm{C}$.
The EMF for the cell reaction, when $0.1 \mathrm{M}$ $\mathrm{Cu}^{2+}$ and $0.1 \mathrm{M} \mathrm{Zn}^{2+}$ solutions are used, at 25 ${ }^{\circ} \mathrm{C}$ is
