  • Why is the thermite reaction an exothermic reaction? - Quora

    This works because the thermite mixture is aluminum powder and iron oxide (rust) powder. When the mixture is heated, it starts reacting: the aluminum is more reactive than the iron, so it "pinches" the oxygen from the iron to make aluminum oxide and iron.
