Exothermic reactions are reactions or processes that release energy, usually in the form of heat or light. In an exothermic reaction, energy is released because the total energy of the products is less than the total energy of the reactants.

Every exothermic reaction is characterized in that the energy levels of its reagents are higher than those of its product , which means that part of the chemical energy contained in its bonds has been released in a new way.

Exothermic reactions are chemical changes that release heat. Combustion and oxidation are the more common examples of this.

Example: Hydrogen is combusted in oxygen. 2H 2 (g) + O 2 (g) → 2H 2 O(g) + energy Exothermic Reactions: “Exo” means exit and thermic means heat, which means the heat energy is released in this reaction, hence the name exothermic. The chemical reaction in which there is a standard change in the enthalpy is termed as exothermic reactions. Endothermic reactions result in an overall positive heat of reaction (\(q_{rxn} > 0\)).
