Kinetics Of Chemical Gas Reactions

Chemical Kinetics of Gas Reactions explores the advances in gas kinetics and thermal, photochemical, electrical discharge, and radiation chemical reactions. This book is composed of 10 chapters, and begins with the presentation of general kinetic rules for simple and complex chemical reactions. The next chapters deal with the experimental methods for evaluating chemical reaction mechanisms and some theories of elementary chemical processes. These topics are followed by discussions on certain class of chemical reactions, including unimolecular, bimolecular, and termolecular reactions. The remaining chapters examine gas reactions, such as molecular collisions, photochemical reactions, chemical reactions in electrical discharge, chain reactions, and combustion. This book will be of value to reaction kinetics engineers and researchers.

Kinetics and Dynamics of Elementary Gas Reactions surveys the state of modern knowledge on elementary gas reactions to understand natural phenomena in terms of molecular behavior. Part 1 of this book describes the theoretical and conceptual background of elementary gas-phase reactions, emphasizing the assumptions and limitations of each theoretical approach, as well as its strengths. In Part 2, selected experimental results are considered to demonstrate the scope of present day techniques and illustrate the application of the theoretical ideas introduced in Part 1. This publication is intended primarily for working kineticists and chemists, but is also beneficial to graduate students.

The present monograph appears after the death of Professor V. N. Kondratiev, one of those scientists who have greatly contributed to the foundation of contem porary gas kinetics. The most fundamental idea of chemical kinetics, put for ward at the beginning of the twentieth century and connected with names such as W. Nernst, M. Bodenstein, N. N. Semenov, and C. N. Hinshelwood, was that the complex chemical reactions are in fact a manifestation of a set of simpler elementary reactions involving but a small number of species. V. N. Kondratiev was one of the first to adopt this idea and to start investigations on the elementary chemical reactions proper. These investigations revealed explicitly that every elementary reaction in turn consisted of many elementary events usually referred to as elementary processes. It took some time to realize that an elementary reaction, represented in a very simple way by a macroscopic kinetic equation, can be described on a microscopic level by a generalized Boltzmann equation. Neverheless, up to the middle of the twentieth century, gas kinetics was mainly concerned with the interpretation of complex chemical reactions via a set of elementary reactions. But later on, the situation changed drastically. First, the conditions for reducing microscopic cquations to macroscopic ones were clearly set up. These are essentially based on the fact that the small perturbations of the Maxwell-Boltzmann distribution are caused by the reaction proper.

Reactions Kinetics: Volume I: Homogeneous Gas Reactions presents a general introduction to the subject of kinetics, including the basic laws of kinetics and the theoretical treatment of reaction rates. This four-chapter book deals mainly with homogeneous reactions in the gas phase. Chapter 1 presents the kinetic laws based on experimental results in terms of their simple concepts, with a special consideration of the way in which rates depend on concentration, while Chapter 2 deals with the interpretation of rates in terms of more fundamental theories. Chapter 3 covers the overall reactions that are believed to be elementary, such as the reaction between hydrogen and iodine, the reverse decomposition of hydrogen iodide, the corresponding reactions involving deuterium instead of hydrogen, and the dimerizations of butadiene and cyclopentadiene, as well as a few elementary termolecular reactions, all involving nitric oxide. This chapter also includes a general account of some of the elementary reactions that occur as steps in more complex mechanisms. Chapter 4 examines the reaction rates of numerous complex gas reactions. Undergraduate physical chemistry and chemical kinetics students, as well as advanced students in other fields, such as biology and physics, will find this book invaluable.

Physical Chemistry: An Advanced Treatise: Kinetics of Gas Reactions, Volume VIB, is devoted to gas phase chemical reactions. The purpose of this treatise is to present a comprehensive treatment of physical chemistry for advanced students and investigators in a reasonably small number of volumes. An attempt has been made to include all important topics in physical chemistry together with borderline subjects which are of particular interest and importance. The book contains six chapters and begins with a study on the elastic and inelastic scattering of ions on molecules, including such topics as rainbow scattering, reactive scattering, and experimental procedures and results of high-resolution measurements. This is followed by separate chapters on collision processes and the theory of elastic scattering; and atom reactions, with a discussion of experimental techniques (static, flow, and pulse methods), among the selected examples being the reactions of H, O, C, and N atoms with alkanes, alkenes, acetylene, sulfur, and nitrogen compounds. Subsequent chapters deal with experimental methods and results obtained by several techniques of relaxation methods in gases; thermal unimolecular reactions; and the interactions between chemical reactions, transport processes, and flow phenomena.
