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

NEETprep Answer:

Using Ellingham diagram, we observe that at temperature greater than 1073 K;

∆ G_{(C, CO)}

<

∆ G_{(Fe, FeO)}

. We know that according to Ellingham diagram, compound having lower

∆_{f} G °

undergo its formation.
Hence, coke can reduce FeO to Fe
