Cabon cannot reduce Fe(2)O(3) to Fe at a...

Cabon cannot reduce `Fe_(2)O_(3)` to Fe at a temperature below 983K because.

A

free energy change for the formation of CO is more negative than that of `Fe_2O_3`

B

CO is thermodynamically more stable than `Fe_2O_3`

C

carbon has higher affinity towards oxygen than iron

D

iron has higher affinity towards oxgen than carbon

Text Solution

Verified by Experts

The correct Answer is:
D
Iron has higher affinity towards oxygen than carbon . So, it cannot reduce `Fe_2O_3` to Fe at a temperature below 983K.
