The thermite reaction is spectacular and exothermic. Iron(III) oxide and metallic aluminum produce molten iron and aluminum oxide in a few seconds. Fe2O3(s) + 2Al(s) → Al2O3(s) + 2Fe(s) Find ΔH for this reaction given the following: 2Al(s) + 3/2O2(g) → Al2O3(s) ΔH = -1670 kJ/mol 2Fe(s) + 3/2O2(g) → Fe2O3(s) ΔH = -822 kJ/mol
