Is breaking a chemical bond exothermic
Web12 sep. 2024 · Heat energy is released when the solute molecules form bonds with the solvent molecules i.e. this process is exothermic. Depending on whether more energy is used to break the bonds within … WebIf your reactions involve covalent bonds, I think the method that would be most relatable at that age is using bond energies: how much energy it takes to break each bond you need to come apart, and how much you get out from making the new bonds. This only gives an approximation, but it’s much easier to explain than some other approaches.
