Web2 de may. de 2024 · Where does the heat from breaking bonds come from? The heat taken in or given out in a reaction comes from the chemical bonds being made or broken in the reaction. If the total energy required to break bonds in the reactants is more than the total energy released when new bonds are formed in the products, it is an endothermic … WebSince breaking bonds requires adding energy, the opposite process of forming new bonds always releases energy. The stronger the bond formed, the more energy is released during the bond formation process.
