If `E_(Fe^(2+)//Fe)^(@) = -0.441 V` and `E_("Fe^(3+)//Fe^(2+))^(@) = 0.771V`, the standard EMF of the reaction
`Fe + 2Fe^(3+) to 3Fe^(2+)` will be:

A

1.212 V

B

0.111 V

C

0.330 V

D

1.653 V

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(Fe^(3+)//Fe)^(@) = -0.441 V`
`E_(Fe^(3+)//Fe)^(@) = -0.771 V`
`= +0.441 + 0.771 = 1.212 V`
