find out the standard enthalpy change.

One reaction involved in the conversion of iron ore to the metal is

FeO (s) + CO (g) à Fe (s) + CO2 (g)

find out the standard enthalpy change for this reaction from these reactions of iron oxides with CO:

(i) 3Fe2O3 (s) + CO (g) à 2Fe3O4 (s) + CO2 (g) ΔH° = -47 kJ
(ii) Fe2O3 (s) + 3CO (g) à 2Fe (s) + 3CO2 (g) ΔH° = -25 kJ
(iii) Fe3O4 (s) + CO (g) à 3FeO (s) + CO2 (g) ΔH° = -19 kJ
