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

Text Solution

Verified by Experts

Using Ellingham diagram, we observe that at temperature greater than 1073 K,
`DeltaG_(C,CO) lt DeltaG_(Fe, FeO)`
We know that, according to Ellingham diagram, compound having lower `Delta_(f)G^(@)` undergo its formation. Hence, coke can reduce FeO to Fe.
