The standard $\mathrm{emf}$for the given cell reaction, $\mathrm{Z}\mathrm{n}+{\mathrm{C}\mathrm{u}}^{2+}\to \mathrm{C}\mathrm{u}+{\mathrm{Z}\mathrm{n}}^{2+}$ is $1.10 \mathrm{V}$ at $25\mathrm{℃}$. The $\mathrm{emf}$for the cell reaction, when $0.1\mathrm{ }\mathrm{M}\mathrm{ }\mathrm{C}{\mathrm{u}}^{2+}$ and $0.1\mathrm{ }\mathrm{M}\mathrm{ }\mathrm{Z}{\mathrm{n}}^{2+}$ solutions are used, at $25\mathrm{℃}$, is
