The average translational kinetic energy of an atom or molecule is about KE = 3/2kT (see Section 13-9), where k = 1.38 × 10-23 J/K is Boltzmann's constant. At what temperature T will KE be on the order of the bond energy (and hence the bond easily broken by thermal motion) for
(a) A covalent bond (say H2) of binding energy 4.0 eV, and
(b) A "weak" hydrogen bond of binding energy 0.12 eV?
