Book Description
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.

Book Description
Physical Chemistry: An Advanced Treatise, Volume VIA: Kinetics of Gas Reactions discusses single reaction steps, such as transformations of atoms and molecules in specified velocities, impact parameters, and inner states into products of specified states. This book is divided into six chapters. Chapter 1 covers formal kinetics, while Chapter 2 reviews the survey of kinetic theory, as one of the bases of reaction kinetics. The Born-Oppenheimer adiabatic approximation, valence bond method, and orbital symmetry in reaction kinetics are elaborated in Chapter 3. Chapter 4 is devoted to the theory of energy transfer in molecular collisions, considering the several possible types of energy exchange. Chapter 5 focuses on the molecular beam scattering experiments on elastic, inelastic, and reactive collisions. The dynamics of bimolecular reactions are elaborated in the last chapter. This volume is intended for graduate and physical chemistry students interested in kinetics of gas reactions.

Book Description
Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it's based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.

Book Description
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.
