For the cell reaction $\displaystyle 2 \mathrm{Fe}^{3+}(\mathrm{aq})+2 \mathrm{I}^{-}(\mathrm{aq}) \rightarrow 2 \mathrm{Fe}^{2+}(\mathrm{aq})+\mathrm{I}_2(\mathrm{aq})$ $\displaystyle \mathrm{E}_{\text {cell }}^{\ominus}=0.24 \mathrm{~V}$ at $\displaystyle 298$ K . The standard Gibbs energy $\displaystyle \left(\Delta_{\mathrm{r}} \mathrm{G}^{\ominus}\right)$ of the cell reaction is : [Given that Faraday constant $\displaystyle \mathrm{F}=96500 \mathrm{C} \mathrm{mol}^{-1}$ ]
