WebSince most chemical transformations do not involve work, the internal energy is mostly a function of the heat that enters or leaves the system. So, when a chemical bond is formed, heat leaves the system, lowering the internal energy of the system. Work must be done to separate atoms in a bond. WebThe energy required to break a specific covalent bond in one mole of gaseous molecules is called the bond energy or the bond dissociation energy. The bond energy for a diatomic molecule, D X – Y, is defined as the standard enthalpy change for the endothermic reaction: (9.4.1) X Y ( g) X ( g) + Y ( g) D X − Y = Δ H ° clarksville hyundai dealership
