This book not only provides practical engineers a handy tool to analyze industrial reactions in the field, but also leads students to handle complicated problems in the classrooms. I used part of the contents in Helfferich's book to teach a graduate-level course on chemical reaction engineering. Everyone was amazed by the powerfulness of the mathematic tools to eluicidate complicated chemical reaction networks.

I applied the tools provided from this book to three different areas: Enzyme reactions, homogenous catalytic reactions and polymeric reactions. The results of such applications are extremely useful for the development of kinetic models. The combination of the theoretical approach in terms of practical mathematics and the experimental consideration from this book is unique and excellent. This book is needed for process engineers in the chemical industry and also provides the industrial approach for kinetic studies that are very useful information for the teaching of reaction kinetics.

This book is one of the very few kinetic books, if not the only one, extensively covering the real-world reactions, which are typically much more complicated than the ideal reactions discussed in textbooks. The book provides very useful tools for reducing a complicated reaction network so that it can be modeled with a manageable number of not only equations (computational load) but also parameters (experimental load). The tools have been successfully applied to a few industrial chemical processes, some of which are discussed in the book as examples. Although this book is intended to be a reference for industrial practitioners it should also be an excellent reference for graduate students working in the field of reaction kinetics/engineering.

This book provides a unique perspective on chemical kinetics. Written by a man who spent most of his career in the chemical process industry, the book never veers very far from practical matters. The treatment of the mathematics of mutlistep reactions is original and cannot be found in any other textbook. I have found these methods to be useful in my research, and they have become an integral part of the kinetics, catalysis, and reaction engineering classes I teach. The book would make a very nice accompaniment to an advanced undergraduate or graduate-level kinetics course.

I have thoroughly enjoyed reading this book, which should become a MUST for every aspiring kineticist. Never have I seen in one place the number of rate equations for such a variety of reaction networks and cycles. The author even gives real chemical examples that fit most of the schemes. What impressed me most is that all are based on more-or-less fundamental principles. For example, in almost every chapter after it was introduced in Chapter 4, specific illustrations of the Bodenstein approximation are given. In addition, there are dozens of good examples from the author's experience at Shell and others' that will be useful to all of us in education.
