WebAug 13, 2024 · The vast majority of naturally occurring reactions are exothermic. In an exothermic reaction, the reactants have a relatively high quantity of energy compared to the products. As the reaction proceeds, energy is released into the surroundings. Low energy can be thought of as providing a greater degree of stability to a chemical system. WebDecomposition reactions can be exothermic or endothermic, depending on the chemical energy of the substances. ... Good question. Actually, burning is an exothermic reaction as it releases heat. The energy which is first given to the system is known as activation energy, the minimum energy required to start the reaction. ...
