Electrochemistry

The standard electrode potential ( $\mathrm{E}^{\circ}$ ) for the half-cell reaction $\mathrm{Fe}^{3+}+\mathrm{e}^{-} \rightarrow \mathrm{Fe}^{2+}$ at 298 K is (Given : $\mathrm{E}^{\circ}\left(\mathrm{Fe}^{3+} / \mathrm{Fe}\right)=-0.04 \mathrm{~V}$ and $\mathrm{E}^{\circ}\left(\mathrm{Fe}^{2+} / \mathrm{Fe}\right)=-0.44 \mathrm{~V}$ at 298 K )
