Enthalpy bonds formed
WebThe enthalpy in the reaction pathway increases as the bonds in the reactants break. The enthalpy then peaks at the transition state. Enthalpy decreases as new form bonds to make the products. The amount of energy required to break bonds and reach the transition state is greater than the amount of energy released when forming new bonds. WebBond enthalpy (which is also known as bond-dissociation enthalpy, average bond energy, or bond strength) describes the amount of energy stored in a bond between atoms in a molecule. Specifically, it's the …
