In the redox reaction

{C r}_{2} O_{7}^{2 -} (a q) + I^{-} (a q) ⟶ {C r}^{3 +} (a q) + I_{2} (s)

, what is the balanced oxidation reaction (before the half reactions are added together)?

Select the correct answer below:

6 e^{-} + 14 H^{+} + {C r}_{2} O_{7}^{2 -} (a q) ⟶ 2 {C r}^{3 +} (a q) + 7 H_{2} O

2 I^{-} (a q) ⟶ I_{2} (s) + 2 e^{-}

2 I^{-} (a q) + 2 e^{-} ⟶ I_{2} (s)

{C r}_{2} O_{7}^{2 -} (q) ⟶ 2 {C r}^{3 +} (a q)
