WebMar 16, 2024 · The existence of the bonds are due to the lower energy state of the bonded atoms in comparison to the isolated atoms. So, to lower the energy or to achieve the more stability the heat should be released. As the formation of bonds increases stability then the reactions are exothermic in nature. Hence, bond formation is always an exothermic … WebChemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture. WebThe energy released is caused by the formation of new bonds (products) at a higher level. While the energy required to break up the bonds (reactants) is lower. ...
