Momentum and energy exchange between species of a multicomponent gas mixture due to inelastic and reactive collisions

Formulas are derived for the rates of change of the number density, momentum, and energy of species due to inelastic and reactive collisions, valid for finite values of the Mach number of the relative motion of the reacting species and for different temperatures of the species. The Wang Chang-Uhlenbeck-de Beer approach is employed. With the aim to make the obtained results more practicable, explicit formulas are given relating the introduced kinetic coefficients to the reaction rate constant, rather than to the reaction cross section.
