The average translational kinetic energy of an atom or molecule is about KE = 3/2 kT (Eq. 13-8), where k = 1.38 X 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 likely to be broken by thermal motion) for
(a) A covalent bond of binding energy 4.5eV (Say H2), and
(b) A ?weak? hydrogen bond of binding energy 0.15eV?
