Paul Houston's Chemical Kinetics and Reaction
Dynamics is a teaching text, not a reference work; an intriguing treat, not
a daunting treatise. The author's aim is to teach the
underlying principles of kinetics and dynamics through relevant
examples and current research. Houston places great stress on the
words modern and clarity. The book is richly illustrated and
nicely balanced. The treatment of essential background
material (chapters on kinetic theory, reaction rates, theories of
chemical reaction, and transport properties) establishes a
firm foundation for the development of specialized
applications (chapters on liquid solutions, solid surfaces,
photochemistry, and molecular reaction dynamics). Houston uses many
clever examples to enhance basic understanding before
introducing more specialized applications. Up-to-date technical
methods are covered in separate sections, appendices, and problem
sets. Extra mathematical detail, if needed, is provided in
appendices at chapter's end. Houston concludes each chapter with
a summary section recapitulating chapter highlights and
key concepts followed by an extensive and useful list of
suggested readings. Problems are generally ample in number; answers
and solutions to a selected number of them are given in the
back. The first few problems in each chapter are mostly
conceptual, of the short-answer or multiple-choice variety. According to
the publisher, a separate solutions manual for all 144 problems
is available as a supplement containing detailed
explanations, diagrams, and references to original sources.
The introduction section is particularly useful for
instructors. Houston breaks the material into fundamental,
supplemental, and advanced topics in a helpful flowchart. He
assigns approximate lecture times to each suggested group
of sections. This is important for instructors who labor
under different semester or quarter lengths. A 14-week semester
easily accommodates the material in the entire text, but much
of the material can be covered in semesters of shorter
duration. Because chapters are mostly independent of each other,
instructors have the flexibility to adapt the text to a variety
of syllabi. The text is suitable for advanced undergraduate
and introductory graduate courses. It is also a useful resource
for instructors of physical chemistry seeking insight into
how chemical reactions occur.
The coverage of essential material is thorough and
complete. I especially appreciate the beginning chapter on
kinetic theory, the underpinning of modern chemical kinetics.
The level of treatment is on par with that in most
physical chemistry textbooks; the number of problems is
ample. Unusual examples within the chapter relate the student
to common experience. In one case, Houston uses the
grade distribution on a class exam for an introduction to
averages; in another, the attraction of bees to honey to illustrate
probability density; and in still another, the size, number,
and speed of skaters on a rink to explore collision
frequency. Mathematics is introduced as needed and explained with
care. The chapter on chemical reaction rates is lengthy and
includes mechanisms as well as rate laws. Important mechanisms,
such as Lindemann for unimolecular decay and
Michaelis-Menten for enzyme catalysis, are treated in depth. The basic
theories of chemical kinetics (collision theory and activated
complex theory) are treated somewhat sketchily in the third
chapter. The material is fleshed out, however, in the problems and
in the applications developed in later chapters. Highlights
of examples from an excellent chapter on transport
properties include the heat flow through fiberglass insulation and
the distance traveled by a gas-phase molecule in one
day by diffusion (contrasted with convection).
Houston begins the chapter on reactions in liquid
solutions with the cage effect, treated on the molecular level
through evolution of cluster growth leading to formation of
solvent. A nifty derivation of the Marcus theory treatment of
electron transfer is another highlight. Experimental
techniques such as temperature jump and ultrafast lasers provide a
nice finishing touch. A few more problems, however, are
needed. The chapter on surface reactions is also
comprehensive and up to date. Important advanced topics covered include
surface diffusion, temperature-programmed desorption, and
modulated molecular beam methods.
Up next is photochemistry, one of Houston's research
specialties. There is excellent material here on photophysical
processes and atmospheric chemistry. Houston develops the
advanced topic of photodissociation dynamics by
providing thoroughly explored sections on pump-probe
techniques, laser-induced fluorescence, multiphoton ionization,
unimolecular dissociation (RRKM theory developed and
applied), photofragment angular distributions, and photochemistry
on very short time scales. Last, but hardly least, is the pièce
de résistance, the capstone chapter on molecular reaction
dynamics. Treated here are sections on chemical lasers,
molecular scattering, potential energy surfaces, and molecular
energy transfer. The chapter ends in a crescendo with superb
performances of orientation effects, bond-selective chemistry,
and van der Waals complexes.
Paul Houston is an outstanding scientist working in the
areas of chemical reaction and photodissociation dynamics;
this book demonstrates that he is a gifted educator as well.
As one who has taught a graduate course in chemical
kinetics on and off for over 25 years, I am eager to put his
text to the test under classroom conditions. For physical
chemists everywhere, Chemical Kinetics and Reaction
Dynamics merits a prominent spot on your bookshelf.
