Answer» For $I_{2} + 2 e^{-} \to 2 I^{-}, standard reduction potential = + 0.54 Volt .$ For $2 B r^{-} \to B r_{2} + 2 e^{-}, standard oxidation potential = - 1.09 Volt .$ For $F e \to F e^{2 +} + 2 e^{-}, standard oxidation potential = + 0.44 Volt .$ Out of the below given reactions, how many reactions are spontaneous in nature (predict from the above data) ? $B r_{2} + 2 I^{-} \to 2 B r^{-} + I_{2}$ $F e + B r_{2} \to F e^{2 +} + 2 B r^{-}$ $F e + I_{2} \to F e^{2 +} + 2 I^{-}$ $I_{2} + 2 B r^{-} \to 2 I^{-} + B r_{2}$
