Abstract

The Montroll-Shuler model for the kinetics of dissociation of a diatomic molecule in a heat bath is adapted to thermal desorption of gases from solid surfaces. The rate constant k_MS is compared with that predicted by transition-state theory, k_TST, and that extracted from experimental data for the system Xe/W. A central feature of the present model is that k _MS shows a strong explicit dependence (θ_D ^-3 in the Debye approximation) upon the lattice dynamics, whereas k_TST has none at all.
