Kinetics of chemical reactions in thermally nonequilibrium gas

Kinetics of chemical reactions without equilibrium between translational and vibrational degrees of freedom in molecules-reagents are considered as two- or multi-temperature gas (mode kinetics) with the conservation of Boltzmann distribution, and as level kinetics without Boltzmann distribution (for populations of different vibrational levels). The listings of kinetics and relaxation equations are presented. The base of models for processes in thermally nonequilibrium dissociation and chemical exchange reactions is provided in terms of the informational fund with intuitive, or empirical, or discursive models of reaction rate constants. The level kinetics models are determined with the interrelations between parameters of these models. The role of thermal nonequilibrium in a solution of chemical kinetics problems is observed.
