Question

What is the bond dissociation energy of the H2 molecule in kilojoules per mole? Given that the H2 molecule has a bond length of 0.74 Angstroms and the energy required to dissociate one mole of H2 into hydrogen atoms is 436 kJ/mol.

Answer 1

The bond dissociation energy of the H2 molecule is the energy required to break the bond between the two hydrogen atoms in one mole of H2 molecules. In this case, the bond dissociation energy is given as 436 kJ/mol. Therefore, the bond dissociation energy of the H2 molecule is 436 kJ/mol.
