###### Problem Details

The thermite reaction, in which powdered aluminum reacts with iron oxide, is highly exothermic. Use the standard enthalpies of formation given to find the ∆H°rxn for the thermite reaction.

2 Al   +   Fe2O3   →   Al2O3   +   2 Fe

∆H Fe2O3 = -824.2 kJ/mol

∆H Al2O3 = -1675.7 kJ/mol
