CHEM301 (Physical Chemistry) Fall 2014
This is an advanced course in Chemistry (and Physics), often abstract and heavily mathematical. Let's hope that the mathematics
never obscures the important physico-chemical principles that we discover. Traditionally, physical chemistry is concerned with
two subject areas: thermodynamics (and its important kinetic theory component), and quantum mechanics. Both subjects are central to the physics
of the atom and of matter, and chemists apply these basic principles to real-world behaviors of chemically-reacting systems. Here, we will exclusively
deal with the thermodynamic side of things.
In some ways, thermodynamics is the most "timeless" branch of physics. It works in the classical realm of slow-moving large things; it works in the
quantum realm of rapidly-moving tiny entities; it can describe electromagnetic radiation; it even has been applied with great success to such exotic situations
as the environment of a black hole! It is essentially the science of energy, and deals with very fundamental questions concerned with the meanings of
heat, and temperature, and whether energy can be used to "do" something, or whether it is irretrievably lost.
Text: Atkins and de Paula Physical Chemistry [ninth edition]. This is a clear and comprehensive text with the status of a true classic.
I encourage you to use the Wells library to scope out other books (and don't limit your search to "chemistry" books -- physical chemistry is as much about physics as it is
about chemistry!). And, it must be said that the internet has become a very good way to obtain factually correct information about topics in science and

Rules of the Game
Attendance is expected at every lecture, as is showing up punctually, so that we can make best use of the time. I expect that you will have read
the material BEFORE the class, to maximize the value of the lecture and discussion. Of course, you are encouraged to bring questions to class, where all
class members will benefit from our conversation about the subtleties of QM. Your grade will be influenced by the level of participation in class. It goes
without saying (but I'll say it anyway) that cell phones are to be turned off, and no laptops may be used except for taking notes, or perhaps the occasional
accessing of some on-line resource.
Grading in this course
Homework/class participation (25%): The set of homework assignments may be
found at Homework Assignment. The homework will be collected and looked over but not graded. If you aren't sure how to do
a particular problem, then ask about it! It is no secret that the solution manual
can be obtained on the web or purchased there, so I will assume that you have access to it.
Exams (50%): 3 of them, 20% each except that the lowest score is weighted 10%.
Final paper/project (25%).
