Iodine and bromine are added to a solution containing `I^(-)` and `Br^(-)` ions. What reaction would occur if the concentration of each species was 1 M ? `[E^(@)(I_(2), I^(-))= 0.54 V, E^(@)(Br_(2), Br^(+))=1.08 V]`

A

`Br^(-) + I_(2) rarr 2Br_(2)+2I^(-)`

B

`I_(2)+Br_(2) rarr 2I^(-)+2Br^(+)`

C

`Br_(2)+2I^(-) rarr 2Br^(-) +I_(2)`

D

`2Br^(-)+2I^(-) rarr I_(2)+Br_(2)`.
