Q. 13
<img width= A. ΔG value for the overall reduction reaction with carbon monoxide is zero.
B. ΔG value for the overall reduction reaction with a mixture of 1 mol carbon and 1 mol oxygen is positive.
C. ΔG value for the overall reduction reaction with a mixture of 2 mol carbon and 1 mol oxygen will be positive.
D. ΔG value for the overall reduction reaction with carbon monoxide is negative.
Answer :
The curve for oxidation of Fe to FeO and CO to CO2 meet at point D and have the same ΔG value.
2Fe+ O2→ 2FeO ---ΔG1
2CO + O2 → 2CO2 --- ΔG2
ΔG1 = ΔG2 because the curves meet at point D.
For reduction of FeO to Fe the sign of ΔG1 must be changed. It becomes - ΔG1. Now the overall ΔGr= - ΔG1 + ΔG2 =0
