Iron metal can be produced in a blast furnace through a complex series of reactions involving reduction of iron(III) oxide with carbon monoxide.overall: iron(III)oxide + carbon monoxide => iron + carbon dioxideUse the equations below to calculate ?Ho for the overall equation.(1) 3Fe2O3(s) + CO(g) => 2Fe3O4(s) + CO2(g) ?H0 = -48.5 kJ(2) Fe(s) + CO2(g) => FeO(s) + CO(g) ?H0 = -11.0 kJ(3) Fe3O4(s) + CO(g) => 3FeO(s) + CO2(g) ?H0 = 22 kJ
