The average bond enthalpy of the O − O bond in ozone is to be calculated. Concept introduction: The amount of energy required to break a particular bond in one mole of gas molecules is known as bond enthalpy. Bond enthalpy is directly proportional to the strength of the bond. Higher the bond enthalpy, stronger is the bond. The breaking of bonds always leads to absorption of energy. Formation of bonds always leads to release of energy. The strength of a bond is determined using the values of bond enthalpy. The process of breaking a bond involves the change of state of the system from higher stability to lower stability, due to which it always requires external energy for its initiation. The process of formation of a bond involves the change of state of the system from lower stability to higher stability due to which it involves the release of energy.
