Following reactions occur spontaneously...

Following reactions occur spontaneously as written below:
`2Fe^(+++)+2l^(-) to 4Fe^(++)+I_(2)`
`O_(2)(g)+H^(+)+4Fe^(++) to 4Fe^(+++)+2H_(2)O`
Oxidizing power of `O_(2),Fe^(+++) and I_(2)` will be in the order:

A

`O_(2) gt Fe^(3+) gt I_(2)`

B

`O_(2) gt I_(2) gt Fe^(3+)`

C

`I_(2) gt O_(2) gt Fe^(3+)`

D

`I_(2) gt Fe^(3+) gt O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Fe^(3+)` undergoes reduction in presence of `I^(-)` but undergoes oxidation in presence of `O_(2)`.
