Abstract
On the basis of a solution of gas-kinetic equations describing the population of molecules (“cut-off” harmonic oscillators) at various oscillatory levels, the process of thermal dissociation has been analyzed. It has been shown that thermal dissociation, in addition to disturbing the Boltzmann distribution, leads to a reduction in the vibrational temperature compared with the translational one. This affects to a considerable extent the rate of thermal dissociation, and also the process of vibrational relaxation. The question of the applicability of the well-known relation of statistical thermodynamics connecting the rate constants of forward and back reactions has also been analyzed. The results obtained agree qualitatively with the experimental data.
