Detailed explanation-1: -Chemical reactions that absorb (or use) energy overall are called endothermic. 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.
Detailed explanation-2: -What is the main difference between an exothermic and an endothermic process? The main difference between exothermic and endothermic reactions is that an endothermic reaction absorbs energy in the form of heat from its surroundings, whereas an exothermic reaction releases energy to the surroundings.
Detailed explanation-3: -What is an Endothermic Reaction? Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
