Answer to Question #96562 in General Chemistry for Mohammad

Question

What is the ΔH° for the following reaction (in kJ/mol of reaction exactly as written)?

2 Al (s) + Fe2O3 (s) → Al2O3 (s) + 2 Fe (s)

To solve, use Appendix II in your textbook (containing standard heats of formation).

Answer 1

2Al(s) Fe2O3(s) → Al2O3(s) 2Fe(l) ΔH = -732.5kJ mol–1
