At temperature above `1073K` coke can be used to reduce `FeO` to `Fe`. How can you justify this reduction with Ellingham diagram?

Text Solution

Verified by Experts

The correct Answer is:
As per Ellingham diagram at temperature greater than `1073 K`
`DeltaG (C, C0) lt DeltaG (Fe, FeO)`. Hence coke can reduce `FeO` to `Fe`.
