The Gibbs energy for the decomposition of `FeO` at `600^@ C` is as follows
`FeO rarr Fe + (1)/(2) O_2 Delta_r G = 856 kJ//"mole"` the potential difference needed for electrolytic reduction of `FeO` at `600^@ C` is at least.

A

`-3.6 V`

B

`-4.73 V`

C

`-5.2 V`

D

`-4.42 V`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta G = - nFE`
`E = (-856 xx 10^3)/(2 xx 96500)`
`E = -4.43 V`.
