A chemical reaction that involves the release of energy in the form of heat or light is known as an exothermic reaction. For example, when carbon burns in presence of oxygen to make carbon dioxide, a large amount of heat is produced. Learn what an exothermic reaction is, how to identify it, and see examples of common exothermic reactions in chemistry and nature. Find out how to calculate the enthalpy change and the activation energy of an exothermic reaction . Conclusion Exothermic reactions show how chemistry can transform the world, one reaction at a time. By releasing energy to their surroundings, exothermic reactions drive everything from warming our hands on a chilly day to fuelling industrial production. Exothermic reactions are chemical reactions that generate heat. The term exothermic is derived from the Greek words Exo, which means outside, and thermic, which means heat. As a result, exothermic heat is heat that moves outside. Exothermic reactions are significant in forensic science, notably in the examination of fires and explosions. Endothermic reactions occur when a chemical reaction demands heat (rather than creating it) and results in the cooling of the surroundings. Exothermic ...
