The (C, CO) line comes below the Fe, FeO line [ΔG (C, CO) < ΔG (Fe, FeO)]. So in this range, coke will be reducing the FeO and will itself be oxidised to CO. In a similar way the reduction of Fe 3 O 4 and Fe 2 O 3 at relatively lower temperatures by CO can be explained on the basis of lower lying points of intersection of their curves with the CO, CO 2
