At temperatures above 1073K coke can be used to reduce FeO to Fe. How can you justify this reduction with the Ellingham diagram?
Options
- AAs per Ellingham diagram at temperatures lower than 1073 K , ∆G(C,CO) < ∆G(Fe,FeO). Hence coke can reduce FeO to Fe.
- BAs per Ellingham diagram at temperatures greater than 1073 K , ∆G(C,CO) < ∆G(Fe,FeO). Hence coke can reduce FeO to Fe.
- CAs per Ellingham diagram at temperatures greater than 1073 K , ∆G(C,CO) > ∆G(Fe,FeO). Hence coke can reduce FeO to Fe.
- DNo,Ellingham diagram cannot provide any justification
Correct answer
B. As per Ellingham diagram at temperatures greater than 1073 K , ∆G(C,CO) < ∆G(Fe,FeO). Hence coke can reduce FeO to Fe.
Step-by-step solution
Correct Option is : (B)
As per Ellingham diagram at temperatures greater than 1073 K , ∆G(C,CO) < ∆G(Fe,FeO). Hence coke can reduce FeO to Fe.
