(a) Consider the following chemical reaction: 3Fe203(s) + C0(g) 2Fe304(s) + CO2(g) AH° = ? Use the following thermochemical data to determine the enthalpy change of this reaction. 4Fe(s) + 302(g) → 2FE2O3 (s) C(s,graphite) + ½O2(g) → CO(g) 3Fe(s) + 202 (g) → Fe3O4(s) CO2(g) → AH° = -1652 kJ AH° = -110.5 kJ AH° = -1117 kJ C(s,graphite) + O2(g) AH° = +395.5 kJ (b) What is the standard enthalpy of formation of carbon dioxide? (2)
