(3) In the iron blast furnace iron(III) oxide is reduced to iron. Coke (carbon) is charged with the ore and air (oxygen) is blown into the furnace, the overall reaction at 1600 °C possibly being: Fe, O, + 3C + 0, - 2Fe + 3CO2 Calculate AH for this reaction at 1600 °C given that the following may be feasible intermediate stages: c+0,CO, CO2 +C3co Fe,O, +coFe, 04 +co, Fe,O, +co2Fe +co2 AH = -593.3 kJ AH = +259.6 kJ AH = -17.6 kJ + 2Fe AH = -10.5 kl
