Question
For the reduction of \[\ce{FeO}\] at the temperature corresponding to point D, which of the following statements is correct?
Options
∆G value for the overall reduction reaction with carbon monoxide is zero.
∆G value for the overall reduction reaction with a mixture of 1 mol carbon and 1 mol oxygen is positive.
∆G value for the overall reduction reaction with a mixture of 2 mol carbon and 1 mol oxygen will be positive.
∆G value for the overall reduction reaction with carbon monoxide is negative.

Solution
∆G value for the overall reduction reaction with carbon monoxide is zero.
Explanation:
At point D, ∆g curve for the formation of \[\ce{CO2}\] from \[\ce{CO}\] and \[\ce{FeO}\] from \[\ce{Fe}\] intersect each other therefore, overall reduction of \[\ce{FeO}\] with \[\ce{CO}\] is zero.
