By Professor Victor N. Kondratiev, Professor Evgeniĭ E. Nikitin (auth.)

The current monograph seems after the dying of Professor V. N. Kondratiev, a kind of scientists who've enormously contributed to the root of contem porary gasoline kinetics. the main primary suggestion of chemical kinetics, placed for ward before everything of the 20 th century and hooked up with names resembling W. Nernst, M. Bodenstein, N. N. Semenov, and C. N. Hinshelwood, used to be that the complicated chemical reactions are in truth a manifestation of a suite of less complicated straightforward reactions regarding yet a small variety of species. V. N. Kondratiev used to be one of many first to undertake this concept and to begin investigations at the effortless chemical reactions right. those investigations published explicitly that each basic response in flip consisted of many undemanding occasions often known as straightforward procedures. It took a while to gain that an ordinary response, represented in a very easy method by means of a macroscopic kinetic equation, will be defined on a microscopic point by means of a generalized Boltzmann equation. Neverheless, as much as the center of the 20 th century, gasoline kinetics used to be mostly keen on the translation of advanced chemical reactions through a suite of straightforward reactions. yet in a while, the placement replaced significantly. First, the stipulations for decreasing microscopic cquations to macroscopic ones have been essentially arrange. those are basically in accordance with the truth that the small perturbations of the Maxwell-Boltzmann distribution are brought on by the response proper.

For example, let the A molecule mass be much lower than that of B. E)2)O ~ [LA [LB (kT)2. Substituting this relation into Eq. 41) and taking into account that here C we obtain the following estimate of the translational relaxation time' = 3k/2 III Theory of Elementary Processes 38 If (J-A/[LB is small, the translational relaxation time may be much larger than the average time between successive collisions. It follows from these considerations that in a mixture of two gases with substantially different molecular masses, for example with [LA ~ (J-n, the relaxation process oceurs via two stages.

Then, the integral equation reduces to the differential FokkerPlanck equation that involves, instead of transition probabilities k(E, E'), the mean square energy change of the relaxing system per unit time [339]. This quantity can be taken as the product of the gaskinetic collision number Zo[B] for molecule A with heat bath molecules B, and the mean square energy change «~E)2) for the relaxing system u;. one collision. «LiE)2) depends on the temperature of the heat bath T and on energy E of the relaxing system before collision.

31) gives equations that can be solved analytically. The study of solutions for different initial distributions provides a fairly general pattern of relaxation. In particular, when the initial distribution is BoUzmannian with temperature T' different from T, it relaxes to the equilibrium Boltzmann distribution via the sequence of Boltzmann distributions with time-dependent temperatures. This relaxation property for harmonic oscillators makes Eq. 40) valid for any deviation of the mean energy from equilibrium.
