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.

Text Solution

Verified by Experts

The correct Answer is:
A
Below point `A`, `Delta_f G^@ (CO, CO_2)` is always more negative than `Delta_f G^@ (Fe, FeO)` and therefore, below point `A`, `FeO` can be reduced by carbon monoxide only as the curve of formation of `CO_2` from `CO` lies below the oxidation curve of `Fe`.
