For reaction $2F{e}^{3+}\left(aq\right)+2I^{-}\left(aq\right)\to 2F{e}^{2+}\left(aq\right)+I_2\left(s\right)$  the magnitude of the standard molar free energy change is ________ kJ 
(Round off to the Nearest Integer)
$E_{\raisebox{1ex}{$F{e}^{2+}$}\!\left/ \!\raisebox{-1ex}{$Fe\left(s\right)$}\right.}^0= -0.44V; E_{\raisebox{1ex}{$F{e}^{3+}$}\!\left/ \!\raisebox{-1ex}{$Fe\left(s\right)$}\right.}^0= -0.036V; E_{\raisebox{1ex}{$I_2$}\!\left/ \!\raisebox{-1ex}{$2I^{-}$}\right.}^0= 0.54V;$$F=96500C$  )
