Appropriate for advanced undergraduate and beginning graduate-level chemistry and chemical engineering courses in kinetics, chemical kinetics, and molecular interpretation. This best selling book offers a balanced presentation of the macroscopic view of empirical kinetics and the microscopic molecular viewpoint of chemical dynamics.* NEW - Revised to include the most up-to-date information throughout. * NEW - Discusses a range of new topics including heterogeneous reactions in atmospheric chemistry, reactant product imaging, and molecular dynamics of H + H2. * NEW - Discusses an experimental observation of the transition state ("Femtochemistry"). * NEW - Presents new treatment of stratospheric chemistry, including heterogeneous processes, balance among catalytic cycles, environmental consequences, and policy implications. * NEW - Presents current database information on NIST kinetics as well as JPL evaluations. * NEW - Separate combustion chapter. FEATURES * Stresses interconnections between phenomenological chemical kinetics and molecular reaction dynamics. * Discusses reactions in gas phase, liquids, and at surfaces; molecular potential surfaces; gas-gas and gas-surface theories applied to reactive collisions. * Features real-world problems and applications to atmospheric chemistry, combustion, and chemical lasers. * Presents multiple methods for solving kinetic equations. * Presents topics not addressed elsewhere. * Information theory. * Stochastic simulation. * Sensitivity analysis. * Includes over 150 figures, tables of Laplace Transforms, and over 125 problems and exercises. *Discusses a range of new topics including heterogeneous reactions in atmospheric chemistry, reactant product imaging, and molecular dynamics of H + H2.*Stresses interconnections between phenomenological chemical kinetics and molecular reaction dynamics.*Presents multiple methods for solving kinetic equations.*Presents topics not addressed elsewhere.*- Information theory; Stochastic simulation; Sensitivity analysis.
