WebSep 11, 2024 · Is a bond breaking reaction exothermic? Breaking these bonds requires energy to be absorbed by the reaction. But then, new bonds form between hydrogen and oxygen and between carbon and oxygen. For this reaction, the energy released is larger than the energy absorbed. WebExothermic reactions are accompanied by an increase in temperature of the reaction mixture. Chemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.

WebAnd exothermic reactions put energy out into the universe. Anabolic reactions are those that build larger molecules, and bond formation releases energy. Catabolic reactions are those that break down molecules into smaller ones, and bond breakage requires energy. So then why are anabolic reactions considered endothermic when they release energy ... WebChemical reactions that absorb (or use) energy overall are called endothermic. In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture. Chris.

WebEnergy must be absorbed to break a bond, so breaking bonds is endothermic.
