The textbook describes the basic concepts and methods of chemical kinetics, the theory of elementary chemical reactions, kinetic patterns of reactions of simple types, complex multistage reactions, catalytic and chain processes. New edition of the textbook (previous published in 1974 . ) is supplemented by the modern theory of monomolecular reactions, ideas about the dynamics of bimolecular processes, about the role of orbital symmetry in elementary reactions . The presentation of the main experimental methods of chemical kinetics - physical methods of registration of reaction components, methods of studying the kinetics of fast-moving processes . has been expanded.
