Question
(a) Consider the following chemical reaction:
3FE203(s) + CO(g)
→ 2Fe304(s) + CO2(g) AH° = ?
Use the following thermochemical data to determine the enthalpy change of this reaction.
- 2FE203 (s)
4Fe(s) + 302(g)
C(s,graphite) + ½O2(g) → CO(g)
3Fe(s) + 202 (g) → Fe304(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?
