Which reaction has positive value of `DeltaG^(@)`?

A

`F_(2)+H_(2)O overset(R.T.)to2HF+(1)/(2)O_(2)uarr`

B

`Cl_(2)+H_(2)O overset(R.T.)toHCl+HOCl`

C

`Br_(2)+H_(2)O overset(R.T.) to HBr+HOBr`

D

`I_(2)+H_(2)O overset(R.T.)toHI+HOI`

Text Solution

Verified by Experts

The correct Answer is:
D

`I_(2)+H_(2)O overset(R.T.) to 2HI+1//2O_(2),DeltaG` of this reaction is positive, hence oxidation of `I^(-)(aq.)` into `I_(2)` is feasible.
