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. Chemical reactions that absorb (or use) energy are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the ... WebApr 23, 2024 · This amount, the bond energy, is roughly the amount of enthalpy necessary to break the bond. Important Concept! An input of energy is always required to break a bond ($\Delta H\gt0$) which means the process is endothermic. Anytime a bond is formed energy is released ($\Delta H\lt0$), so forming bonds is exothermic.
