In the smelting of iron ores, the reduction of iron oxides in a blast furnace is accompanied by the oxidation of CO(g) to CO2(g). The three reactions leading to the formation of Fe are: Reaction (i): 3 Fe,03(s) + CO(g) → 2 Fe304(s) + CO2(9) Reaction (ii): Fe3O4(s) + CO(g) → 3 FeO(s) + CO2(9) Reaction (iii): FeO(s) + CO(g) → Fe (s) + CO2(g) The graph below shows the variation of the Gibbs energy change with temperature for each of these reactions.
