Zusatztext The book is a first-class scholarly monograph." Faraday Transactions Informationen zum Autor Peter Gray is also Visiting Professor, University of Leeds Klappentext Today! scientists in many fields are expressing considerable interest in non-linearity and the ideas of oscillations and chaos. Chemical reactions provide perfect examples of these phenomena. This book is an excellent introduction to the area of nonlinear phenomena in chemical kinetics thatinvolve chemical feedback such as chain branching! autocatalysis! and self-heating. The emphasis is on physical and pictorial representation! and on identifying those gross features which are essential. The experimental conditions under which such behavior will occur can be predicted using simplemathematical recipes! and these are also included. Readers will find full discussions of long-lived oscillations for autocatalytic or exothermic reactions in closed vessels and stationary states! bistability! and oscillations in continuous flow reactors and diffusion cells. Other topics consideredinclude chemical wave propagation! pattern selection and formation! heterogeneous reactions! complex oscillations! quasiperiodicity! and chemical chaos! both forced and spontaneous. The second part of the book describes actual experimental systems! such as the Belousov-Zhabotinskii reaction! andinclude discussion of the behavior of important gas-phase reactions. This volume is an ideal sourcebook of applied problems for graduate courses in dynamical systems! advanced chemical kinetics! and chemical reactor engineering! as well as for research workers in physical chemistry! andmathematicians! biologists! physicists! and physiologists. Zusammenfassung Scientists in many fields are now expressing considerable interest in non-linearity and the ideas of oscillations and chaos. Chemical reactions provide perfect examples of these phenomena, as oscillating reactions, explosions, ignition, travelling waves, patterns, quasiperiodicity, and chaos are all features of chemical kinetics.^Now available in paperback, this book introduces non-linear phenomena in chemical kinetics using simple model schemes. These models involve chemical feedback, such as chain branching, autocatalysis, and self-heating. The emphasis is on physical and pictorial representation, and on identifying those gross features which are essential. The experimental conditions under which such behaviour will occur can be predicted using simple mathematical recipes, and these are also included.^The first part of the book begins with a discussion of long-lived oscillations for autocatalytic or exothermic reactions in closed vessels. Stationary states, bistability, and oscillations in continuous flow reactors and diffusion cells are then considered. This is followed by chemical wave propagation and by pattern selection and oscillations. Complex oscillations, quasiperiodicity, and chemical chaos, either forced or spontaneous, are introduced. Part 2 deals with real experimental systems, describing observed experimental behaviour and its interpretation in terms of the underlying chemical mechanisms or simplified models. The Belousov-Zhabotinskii reactions is discussed in some detail as the most extensively studied system, and the behaviour of important gas phase reactions is presented.
