WebChemical reactions, in which chemical bonds are broken and formed, require an initial investment of energy. Kinetic energy, the energy of matter in motion, fuels the collisions of atoms, ions, and molecules that are necessary if their old … WebWhen a chemical reaction releases more energy than it absorbs, it is called an exothermic reaction. In an exothermic reaction, the products have lower bond energies than the reactants. The excess energy – the difference in bond energy between the reactants and the products – is often given off as heat or light. 14.
