In the blast furnace for manufacturing iron, most of the reduction is carried out by CO rather than C (coke). How can you account for this?

Text Solution

Verified by Experts

The correct Answer is:
From the ellingham diagram, it can be seen that CO can reduce iron oxide at lower termperature whereas carbon can reduce iron oxide only above 1073K.
