WebJul 17, 2024 · In all types of chemical reactions, bonds are broken and reassembled to form new products. However, in exothermic, endothermic, and all chemical reactions, it takes energy to break the existing chemical bonds and energy is released when the new bonds form. Breaking Bonds → Energy Absorbed. WebIn a chemical reaction, chemical bonds are broken in the reactants and new chemical bonds are formed in the products. Breaking bonds requires energy, whereas forming bonds allows energy to be released. In some reactions the energy required to break bonds is greater than the energy released as new bonds form. For such a reaction to proceed ...
