Question

For the reaction

2Fe³⁺(aq) + 2I^$-$(aq) $ \to $ 2Fe²⁺(aq) + I₂(s)

the magnitude of the standard molar Gibbs free energy change, $\Delta$_rG$_m^o$ = $-$ ___________ kJ (Round off to the Nearest Integer).

$$\left[ {\matrix{ {E_{F{e^{2 + }}/Fe(s)}^o = - 0.440V;} & {E_{F{e^{3 + }}/Fe(s)}^o = - 0.036V} \cr {E_{{I_2}/2{I^ - }}^o = 0.539V;} & {F = 96500C} \cr } } \right]$$
