The bond dissociation energy is the energy required to break a bond between two atoms. In this case, we are given the average H-H bond energy, which is 436 kJ/mol. Since there is only one H-H bond in a hydrogen molecule H2 , the bond dissociation energy is equal to the average bond energy.Here are the steps to calculate the bond dissociation energy for the H-H bond:1. Identify the bond: In this case, it's the H-H bond in a hydrogen molecule H2 .2. Find the average bond energy: We are given that the average H-H bond energy is 436 kJ/mol.3. Calculate the bond dissociation energy: Since there is only one H-H bond in the hydrogen molecule, the bond dissociation energy is equal to the average bond energy.Bond dissociation energy H-H = Average bond energy H-H Bond dissociation energy H-H = 436 kJ/molSo, the bond dissociation energy for the H-H bond is 436 kJ/mol.
