Detailed explanation-1: -In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

Detailed explanation-2: -An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur.

Detailed explanation-3: -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. Chemical reactions that absorb (or use) energy are called endothermic.

Detailed explanation-4: -A chemical reaction in which heat is released is called an exothermic reaction. A chemical reaction in which heat is absorbed is called an endothermic reaction.
