For a diatomic molecule like H2, the enthalpy of atomization equals its:
ALattice enthalpy of solid
BFirst ionization enthalpy
CBond dissociation enthalpy
DStandard enthalpy of formation
Answer & Solution
Correct answer: C. Bond dissociation enthalpy
Atomizing a diatomic molecule breaks exactly one bond, so it equals the bond dissociation enthalpy.
