Below point 'A' `FeO` can __________
(a)be reduced by carbon monoxide only.
(b)Be reduced by both carbon monoxide and carbon.
(c)be reduced by carbon only
(d)not be reduced by both carbon and carbon monoxide

A

be reduced by carbon monoxide only.

B

Be reduced by both carbon monoxide and carbon.

C

be reduced by carbon only

D

not be reduced by both carbon and carbon monoxide

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Below point A Gibbs free energy change for the formation of `CO_(2)` from `CO Delta_((Co,CO_(2))^(@)` has lower value (more negative value) than Gibbs free energy change for the formation of `FeDeltaG_((Fe,FeO))` Hence, FeO will be reduced by CO only below point A.
