# Problem: The following is known as the thermite reaction: 2 Al(s) + Fe2O3(s) → Al2O3 (s) + 2 Fe(s)This highly exothermic reaction is used for welding massive units, such as propellers for large ships. Using enthalpies of formation in Appendix C, calculate ΔH˚ for this reaction.

###### FREE Expert Solution

We are asked to calculate the value of ΔH˚ for 2 Al(s) + Fe2O3(s) → Al2O3 (s) + 2 Fe(s)

Note that we need to multiply each ΔH˚ by the stoichiometric coefficient since ΔH˚ is in kJ/mol.
