For the reducetion of FeO at the temperature corresponding to point D, which of the following statements is correct ?

Options

A. 1. `DeltaG^(@)` value for the overall reduction with carbon monoxide is zero.
B. 2. `DeltaG^(@)` value for the overall reduction reaction with a mixture of 1 mol carbon and 1 mol oxygen is positive .
C. 3. `DeltaG^(@)` value for the overall reduction reaction with a mixture of 2 mol carbon and 1 mol oxygen will be positive.
D. 4. `DeltaG^(@)` value for the overall reduction reaction with carbon monoxide is negative

Answer

A

Explanation

At point D both the curves of oxidation of Fe and oxdiaton of CO intersect, therefore at this point , `DeltaG^(@)` value for the overall reduction of FeO to Fe with CO is zero.
