Question

Calculate the bond energy of O-O bond in a molecule of oxygen gas (O$_2$) given that the dissociation energy required to break this bond is 498 kJ/mol.

Answer 1

The bond energy of the O-O bond in a molecule of oxygen gas  O  is equal to the dissociation energy required to break the bond. In this case, the dissociation energy is given as 498 kJ/mol. Therefore, the bond energy of the O-O bond in O is also 498 kJ/mol.
