An exothermic reaction is a chemical reaction that releases energy by light or heat it is the opposite of an endothermic reaction expressed in a chemical equation. Endothermic reactions endothermic reactions absorb heat, meaning the reaction uses more heat than is released in its products chemical reactions require energy to. The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings usually, but not always, in the form of heat.
