Assertion : At temperature above 1073 K (approx.) the `C,CO` line comes below the `Fe, FeO` line `[DeltaG_((C,CO)) lt DeltaG_((Fe,FeO))]`
Reason : In this range, coke will reduce the FeO and itself get oxidised to CO. : If both (A) and (R) are correct and (R) is the correct explanation of(A)., If both (A) and (R) are correct, but (R) is not the correct explanation of (A)., If (A) is correct, but (R) is incorrect., If both (A) and (R) are incorrect.

A

Statement 1 is True, Statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
B
At temperature above 1073 K (approx.) the C, CO line comes below the Fe, FeO line `[Delta_((Fe,FeO)) gt Delta G_((C,CO))]`. So, this range, coke will reduce the FeO and will itself oxidised to CO.
