$2 \mathrm{Fe}^{3+}(\mathrm{aq})+2 \mathrm{I^-}(\mathrm{aq}) \rightarrow 2 \mathrm{Fe}^{2+}(\mathrm{aq})+\mathrm{I}_{2}(\mathrm{aq})$
$\mathrm{E}_{\text {call }}^{\mathrm{e}}=0.24 \mathrm{V}$ at $298\; \mathrm{K}$. The standard Gibbs energy $\left( {{\Delta _r}{{\rm{G}}^ \ominus }} \right)$ of the cell reaction is:
[Faraday constant $\mathrm{F}=96500 \;\mathrm{C} \mathrm{mol}^{-1} $]

$C{l_2} + 2{Y^ - } \to \,2C{l^ - }\, + \,{Y_2}$
The incorrect match regarding above reaction is
$PhCHO + Ph \cdot CHO \xrightarrow[in\,\,{{D}_{2}}O]{NaOD} A + \begin{matrix} O \\ || \\ Ph-C-{{O}^{-}} \\ \end{matrix}$$\left( Ph\right.$ is $\left.- C _{6} H _{5}\right)$
