Detailed explanation-1: -Breaking chemical bonds is endothermic, a process that requires an input of energy or absorption of heat. The reverse process of bond breaking is bond formation, which is exothermic, meaning it releases energy or gives off heat.
Detailed explanation-2: -Chemical 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.
Detailed explanation-3: -A chemical reaction occurs when chemical bonds are broken and formed and atoms are exchanged to produce chemically different species. Both of these processes are chemical reactions.
