Exothermic reaction

In chemistry, an exothermic reaction is one that releases heat. Expressed in a chemical equation:

Reactants → Products + Energy

When using a calorimeter, the change in heat of the calorimeter is equal to the opposite of the change in heat of the system. This means that when the solution in which the reaction is taking place gains heat, the reaction is exothermic.

An exothermic reaction is the opposite of an endothermic reaction.
