Given the following data:  Fe2O3(s)  + 3CO(g) —–> 2Fe(s) + 3CO2(g)         ΔH° = – 23 kJ  3Fe2O3(s) +  CO(g) ——> 2Fe3O4 (s) + CO2(g)    ΔH° = – 39 kJ   Fe3O4(s) +  CO(g) ——->  3FeO(s) + CO2(g)      ΔH° = – 18 kJ  Calculate the ΔH° for the reaction.  FeO(s)  + CO(g) ——–> Fe(s) + CO2(g) 

Consider the reaction:   2SO₂(g) + O₂(g) → 2SO₃(g)carried out at 25°C and 1 atm. Calculate ΔH°, ΔS°, and ΔG° using the following data:SubstanceΔH°f (kJ/mol)S° (J/K·mol)SO₂(g)-297248SO₃(g)-396257O₂(g)0205

 Given the following data:  Fe2O3(s)  + 3CO(g) —–> 2Fe(s) + 3CO2(g)         ΔH° = – 23 kJ  3Fe2O3(s) +  CO(g) ——> 2Fe3O4 (s) + CO2(g)    ΔH° = – 39 kJ   Fe3O4(s) +  CO(g) ——->  3FeO(s) + CO2(g)      ΔH° = – 18 kJ  Calculate the ΔH° for the reaction.  FeO(s)  + CO(g) ——–> Fe(s) + CO2(g)
