${E^o}_{\left( {{I_2}/{I^ - }} \right)},{E^ \circ }_{\left( {Br^-/B{r_2}} \right)}$ and ${E^ o }_{\left( {{Fe}/{Fe^{2+} }} \right)}$
are respectively $+ 0.54\ V$, $-1.09\ V$ and $0.44\ V$. On the basis of above data which of the following process is non-spontaneous
$\text{E}_{\text{cell }}^{o}=\left( \text{E}_{\text{Rp}}^{{}^o } \right)\text{ cathode }-{{\left( \text{E}_{\text{RP}}^{{}^o } \right)}_{\text{anode }}}$
$\because \,\,\,\text{E}_{\text{cell}}^{o}$ is negative hence this reaction is non-spontaneous
