Standard reduction potentials of the half reactions are given below :
$F_{2} (g) + 2 e^{-} \to 2 F^{-} (a q); E^{\circ} = + 2.85 V$
$C l_{2} (g) + 2 e^{-} \to 2 C l^{-} (a q); E^{\circ} = + 1.36 V$
$B r_{2} (l) + 2 e^{-} \to 2 B r^{-} (a q); E^{\circ} = + 1.06 V$
$I_{2} (s) + 2 e^{-} \to 2 I^{-} (a q); E^{\circ} = + 0.53 V$
