WebSep 11, 2024 · Bond breaking is an endothermic process, because it requires energy. Bond forming is an exothermic process, because it releases energy. In reaction profile diagram, the energy change in a reaction, is the difference between the reactants and products. Table of Contents show Is a bond breaking reaction exothermic? WebAug 10, 2024 · Chemical processes are labeled as exothermic or endothermic based on whether they give off or absorb energy, respectively. Atoms are held together by a certain amount of energy called bond energy. Energy is released to generate bonds, which is why the enthalpy change for breaking bonds is positive. Energy is required to break bonds.
WebDec 29, 2024 · The formation of new bonds is exothermic, so depending on whether the old bonds or the new bonds were stronger, the reaction overall can be either endothermic or exothermic. When somebody says chemical bonds “contain potential energy” it is a HIGHLY misleading statement. WebAuthor has 116 answers and 543.4K answer views 6 y.
