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 The exothermic reaction is the opposite of an endothermic reaction . It releases energy by light or heat to its surrounding. A few examples are neutralisation, burning a substance, reactions of fuels, deposition of dry ice, respiration, solution of sulphuric acid into water and much more. The term ‘Exo’ refers to ‘to release,’ and ‘thermic’ refers to ‘heat.’ The energy released is caused by the formation of new bonds (products) at a higher level. While the ... 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. Exothermic Reaction is a chemical reaction that releases energy in the form of heat to its surroundings. Common examples of exothermic reactions include combustion reactions , where substances burn and produce heat as a byproduct, such as the burning of wood or the combustion of gasoline in an engine.
