Book excerpt: Many books cover the determination of rate constants under different experimental conditions and different chemical composition of the reaction mixture in their formal treatment of thermal kinetics. However, most textbooks are limited to simple mechanisms. In contrast, analogous treatment of photochemical reactions is limited to the publication of special reactions and investigations. Therefore, this book is aimed at providing an overall description of formal photokinetics covering a wider scope than the usual books on kinetics.This volume attempts to provide a concise treatment of both thermo- and photochemical reactions by means of generalised differential equations, their set-up in matrix notation, and their solution by a formalism using numerical integration. At a first glance this approach might be surprising. However, apart from the argument that the didactics of thermal reactions are easier to handle than those of kinetics, the book provides additional reasons in support of this approach. Therefore, the formalism derived allows the evaluation of photochemical reactions, which are superimposed thermal reactions taking into account that the amount of light absorbed varies during the reaction. Because of this, any approximation, either by using total absorbance or negligible absorbance, will cause considerable errors even for simple reactions. The approach chosen to transform the axis of the radiation time into a new variable that includes the photokinetic factor proves that formal kinetics can be applied to thermal and photochemical reactions as well, and even allows the handling of solutions that cannot be homogenised or solid samples in which the concentration varies locally. By using this approach to introduce partial photochemical quantum yields even complex mechanisms can be determined quantitatively.A large number of examples for different mechanisms and an introduction to many spectroscopic and chromatographic methods suitable for photokinetic analyses are provided to enable the reader to carry out a step-by-step evaluation of his own measurements. To reduce the number of formula in some chapters an appendix has been included which contains a detailed description of the calculus of some essential examples. For the convenience of the reader the following has been included:• A large number of examples describing the use of formula• A detailed description of the procedure for applying photokinetics to complex consecutive photoreactions• An Internet address where the reader can find a tutorial for this procedure:http://www.barolo.ipc.uni-tuebingen.de/tele/photokin/• A simple macro to help in programming his own evaluation procedure.

Book Synopsis Kinetics of Homogeneous Multistep Reactions by : Friedrich G. Helfferich
Download or read book Kinetics of Homogeneous Multistep Reactions written by Friedrich G. Helfferich and published by Elsevier. This book was released on 2001-01-25 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses primarily the chemist and engineer in industrial research and process development, where competitive pressures put a premium on scale-up by large factors to cut development time. To be safe, such scale-up should be based on "fundamental" kinetics, that is, mathematics that reflect the elementary steps of which the reactions consist. The book forges fundamental kinetics into a practical tool by presenting new effective methods for elucidation of mechanisms and reduction of mathematical complexity without unacceptable sacrifice in accuracy.
Book Synopsis Kinetics of Multistep Reactions by : Friedrich G. Helfferich
Download or read book Kinetics of Multistep Reactions written by Friedrich G. Helfferich and published by Elsevier. This book was released on 2004-09-15 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses primarily the engineer in industrial process development, the research chemist in academia and industry, and the graduate student intending to become a reaction engineer. In industry, competitive pressures put a premium on scale-up by large factors to cut development time. To be safe, such development should be based on "fundamental" kinetics that reflect the elementary steps of which the reaction consists. The book forges fundamental kinetics into a practical tool by presenting new, effective methods for elucidation of mechanisms and reduction of complexity without unacceptable sacrifice in accuracy: fewer equations (lesser computational load), fewer coefficients (fewer experiment to determine them). For network elucidation, new rules relating network configurations to observable kinetic behaviour allow incorrect networks to be ruled out by whole classes instead of one by one. For modelling, general equations and algorithms are given from which equations for specific networks can be recovered by simple substitutions. The procedures are illustrated with examples of industrial reactions including, among others, paraffin oxidation, ethoxylation, hydroformylation, hydrocyanation, shape-selective catalysis, ethane pyrolysis, styrene polymerization, and ethene oligomerization. Many of the rate equations have not been published before. The expanded edition of the 2001 title, Kinetics of Homogeneous Multistep Reactions includes new chapters on heterogeneous catalysis and periodic and chaotic re-actions; new sections on adsorption, statistical methods, and lumping; and other new detail. - Contains new chapters on heterogeneous catalysis, oscillations and chaos - Includes new sections on statistical methods, lumping adsorption and software and databases - Provides a better understanding of complex reaction mechanisms
Book Synopsis Modeling of Chemical Reactions by : R.W. Carr
Download or read book Modeling of Chemical Reactions written by R.W. Carr and published by Elsevier. This book was released on 2007-09-04 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling of Chemical Reactions covers detailed chemical kinetics models for chemical reactions. Including a comprehensive treatment of pressure dependent reactions, which are frequently not incorporated into detailed chemical kinetic models, and the use of modern computational quantum chemistry, which has recently become an extraordinarily useful component of the reaction kinetics toolkit. It is intended both for those who need to model complex chemical reaction processes but have little background in the area, and those who are already have experience and would benefit from having a wide range of useful material gathered in one volume. The range of subject matter is wider than that found in many previous treatments of this subject. The technical level of the material is also quite wide, so that non-experts can gain a grasp of fundamentals, and experts also can find the book useful. - A solid introduction to kinetics - Material on computational quantum chemistry, an important new area for kinetics - Contains a chapter on construction of mechanisms, an approach only found in this book
Book Synopsis Comprehensive Chemical Kinetics by : Nicholas Green
Download or read book Comprehensive Chemical Kinetics written by Nicholas Green and published by Elsevier. This book was released on 2003-11-21 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unimolecular reactions are in principle the simplest chemical reactions, because they only involve one molecule. The basic mechanism, in which the competition between the chemical reaction step and a collisional deactivation leads to a pressure-dependent coefficient, has been understood for a long time. However, this is a rapidly developing field, and many new and important discoveries have been made in the past decade.This First Part Part of Two CCK Volumes dealing with Unimolecular Rections, deals with the Reaction Step. The first chapter is an introduction to the whole project, aiming to cover the material necessary to understand the content of the detailed chapters, as well as the history of the development of the area. Chapter 2 is a review of the modern view of the statistical theories, as embodied in the various forms of RRKM theory. Chapter 3 deals with the fully quantum mechanical view of reactive states as resonances.. Presents considerable advances in the field made during the last decade.. Treats both the statistical as well as the fully quantum mechanical view.
