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

Answer»

`DeltaG^(@)` value for the overall reduction reaction with carbon monoxide is ZERO. 
`DeltaG^(@)` value for the overall reduction reaction with a mixture of 1 mol carbon and 1 mol oxygen is positive.
`DeltaG^(@)` value for the overall reduction reaction with a mixture of 2 mol carbon and 1 mol oxygen will be positive.
`DeltaG^(@)` value for the overall reduction reaction with carbon monoxide is NEGATIVE.

Solution :At POINT `D, DeltaG_((CO","CO_2))^(@) = Delta_(f)G_((Fe","FeO))^(THETA)`
Thus overall value of `DeltaG^(@)` will be zero.
