Chapter 1 comes with all the modules. The Statistical Mechanics chapter, 15, was completely re-written by Professor Bryan Sanctuary. You can see the detailed Table of Contents by clicking the "Contents" tab just above this text. Only available in dowload format, this chapter covers equilibrium statistical mechanics from the most fundamental starting point and leads the student through the beauty of how statistical methods describe the collective dynamics of microscopic particles which leads to those few macroscopic thermodynamics functions they have learned about.
The approach taken in presenting the basic ideas is to start with the microcanonical ensemble. Traditionally stat. mech. is introduced using the canoncial ensemble. An advantage, for the author at least, is that a study of the microcanoncial ensemble gives a clear and satisfying way of understanding entropy. This approach helps students to get a deeper view of entropy. In the end, however, the Lagendre Transformation relates them all, so with canonical or microcanonical, we get to the same result.
Extensive and detailed examples are worked out in order to make sense out of difficult concepts, like the statistical treatment of degeneracy. The work, however, is not all theory and gives the standard relationships between thermodynamic quantities and partition functions. The translational, rotational, etc. modes are evaluated for special cases, and application to equilibrium constants and Transition State Theory are developed. Finally there is an appendix on Combinatorials and many new problems.
Download the Statistical Mechanics Solutions Manual for free. It contains the solutions to all the problems as worked out by students themselves. This peer learning model is a valuable asset for students. Check for up-dates.
The programs can be installed and run on a variety of system configurations. The minimum requirements are described below for PCs and MACs.

Engaging multimedia pop-ups.
Much cheaper than hard copy textbooks, and the options of buying smaller modules at even greater savings.
Target audience
Covers all the traditional and modern topics in Physical Chemistry in undergraduate physical science programs.
We encourage sales to Universities, Institutions and Home Groups by providing
Volume Discounts (found at the bottom of all product pages). These provide even greater savings over our already low prices, compared to hard copy textbooks.
Users: teachers
With the programs loaded on the teachers laptop, the material can be projected in class. In addition throughout the text are scattered about 100 multimedia interactions that pop-up. In class, using the Multimedia Table of Contents , these interactions can be used as demonstrations.
Easy navigation with all sections and subsections linked to the Table of Contents..
Integrated into The Web with ready links to websites like Wikipedia, Google search, More Chemistry Help, etc.
In the flash version, an oular tool allows for important sections of the text to be highlighted and magnified, with the rest of the text dimmed. This is useful for students to keep their place while reading and for teachers to emphasize a point in class.
The multimedia pop-ups give students a chance to visualize and interact with programs that demonstrate different concepts.
The text provides detailed treatment of concepts that students often find challenging. Most of these are illustrated by worked examples.
eBooks are
green and today students have grown up reading and interacting with computers. Students are not only comfortable with electronic media, but for ecological reasons alone, eBook must replace hard copy.
Users: Students
This eTextbook provides many more features than are possible with hard textbooks, and does this at a much reduced price. Although all the undergraduate topics in physical chemistry are covered, you may not need to take them all. For this reason, the textbook is broken into smaller modules that cover specific topics. This provides an even greater saving.
Easy navigation, convenient hyperlinking and many features that enhance your ability to find material easily so you can concentrate on learning.
Fully integrated into The Web, with links to Wikipedia, Google, More Chemistry Help, and other useful on-line resources.
Interesting and informative multimedia components are built into the book and pop-up when clicked so you can listen to explanations of the material you are working on, and perform interactions that will help you understand the concepts.
In the flash version, a reading ocular allows you to magnify and focus on specific areas of text material. This helps you to keep your place while reading. In addition there is an underline tool that permits you to highlight text.
Note-taking tool allows you to jot down your thoughts as you go, or to keep reminders. (Flash version only)
Extensive problems are provided that are an essential part of studying for Physical Chemistry. A full solution manual is available for free. This solution manual was written by students for students. It is well known that peer learning is effective, and therefore the worked-out problems provide a valuable tool for all those interested in understanding physical chemistry at the required level.
