Exothermic reaction. 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: reactants â products + energy. Exothermic Reaction means exo meaning releases and thermic means heat. So the reaction in which there is release of heat with or without light is called exothermic reaction.
This page was created to possibly help others who don't understand endothermic and exothermic reactions as well as they want or need to. The basic definitions are easy to understand: Endothermic: a reaction or process which absorbs heat from its surroundings. Exothermic: a reaction or process which gives off heat to its surroundings. The problem comes in trying to state which specific examples of reactions are which, because usually a lot of things are going on at the same time.
