Unfortunately, you did not specify what final chemical equation you wanted given these formulas. From the data though I assumed the following: Fe2O3(s) + 3CO(g) à 2Fe(s) + 3CO2 H1 3Fe2O3(s) + CO(g) à 2Fe3O4(s) + CO2(g) H2 Fe3O4(s) + CO(g) à 3FeO(s) + CO2(g) H3 3(Fe2O3(s) + 3CO(g) à 2Fe(s) + 3CO2) 3(H1) 2Fe3O4(s) + CO2(g) à3Fe2O3(s) + CO(g) -H2 2(3FeO(s) + CO2(g) à Fe3O4(s) + CO(g)) 2(-H3) 3Fe2O3(s) + 9 (6)CO(g) à 6Fe(s) + 9(6)CO2 3(H1) 2Fe3O4(s) + CO2(g) à3Fe2O3(s) + CO(g) -H2 6FeO(s) + 2CO2(g) à 2Fe3O4(s) + 2CO(g) 2(-H3) 6FeO(s) + 6CO(g) à 6Fe(s) + 6CO2 3H1 + -H2 + -2H3 FeO(s) + CO(g) à Fe(s) + CO2 [(3H1 + -H2 + -2H3) / 6] FeO(s) + CO(g) à Fe(s) + CO2 -11KJ/mol
