WebSep 9, 2024 · Chemical 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. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture. Why is a reaction exothermic in terms of bond … WebIs bond breaking exothermic? nope bond breaking is a ENDOTHERMIC PROCESS because during bond breaking we provide heat which is absorbed by the bond …
WebAn exothermic reaction is a chemical reaction that releases energy in the form of heat or light. During an exothermic reaction, the reactants have more energy stored in their chemical bonds than the products, so the excess energy is released into the surroundings, resulting in an increase in temperature. In an exothermic reaction, the enthalpy ... WebThe energy is released to reduce the energy or achieve greater stability. For breaking a bond energy is provided to the bonded atoms. They gain energy and break their bonds. The energy is mostly heat energy and light energy. Thus, breaking of bond is an endothermic process, not an exothermic process. Suggest Corrections.
