Class meets: MWF 10:10-11:05am in SCST 129
Optional Class Text: Any Physical Chemistry textbook for your reference. Popular ones include Atkins and de Paula; Engel and Reid; McQuarrie and Simon; Levine; Barrow; Silbey and Alberty. I will not be following a textbook closely so it does not matter which one you use as a reference if you so choose.

Why should I care? What is thermodynamics? Does the Second Law of Thermodynamics constrain me to get progressively disorganized and messy as life goes on? Does everything that we observe hinge simply on statistics and what is most probable? How do you count zillions and zillions of probability states anyway and why should I bother? If you've ever asked yourself any of these questions, then this course will begin to answer some of them, but it will also bring up more nagging, but vitally interesting, questions!
Course goals: To understand and apply thermodynamics and kinetics to chemistry. This course will begin with the study of gases as an example of how microscopic properties relate to macroscopic properties. It will then cover the first three laws of thermodynamics, free energy, and kinetics.
Learning outcomes:
At the end of the course you will be able to derive the molecular properties of thermodynamics from statistical mechanics and apply this knowledge to solve various chemical problems, both macroscopic and microscopic, involving thermodynamics and kinetics.
More specifically you should be able to:
1. derive and apply thermodynamic expressions based on equations of state
2. apply the conceptual and theoretical tenets of the three laws of thermodynamics
3. apply the concepts of enthalpy, entropy, free energy, and their relationships to thermochemistry and equilibrium
4. derive and apply the equations of statistical mechanics to bridge the microscopic and macroscopic views of molecular behavior
5. derive and apply the equations that describe the molecular and macroscopic aspects of chemical rate laws
6. apply the concepts of thermodynamics to the various states of matter, their transitions, and to mixtures
Course requirements:
1. There will be three in-class exams and one Final Exam. There will
be seven problem sets which you will turn in.
There will be many worksheets, some of which we will do in-class and some of which
(approximately twelve) you will turn in for a grade.
2. A good grasp of calculus is important for understanding the material and completing the problem sets and exams. It is your responsibility to refamiliarize yourself with your calculus text if you need a refresher. You are also expected to be familiar with anything covered in General Chemistry (CHEM151 and CHEM152).
3a. Collaboration is allowed, and even encouraged, on problem sets and worksheets but each student must write
up their own work. I am not as interested in whether you got the right
answer but how you arrived at your answer. Intermediate steps must be shown.
3b. There will be NO collaboration on any exam. You do need to really understand the material deep down in your very own self.
4a. Grade breakdown is as follows:
7 Problem Sets @ 2% each 14%
12 Worksheets @ 0.5% each 6%
3 Exams @ 16% each
48%
Final Exam
32%
4b. Tentative Grading Scale (subject to change by the instructor at
any time)
A 85-100%
B 70-84%
C 55-69%
D 40-54%
F 0-39%
Appended + and - will approximately constitute 3% widths at either
end of the scale for A-D grades.
5a. Late problem sets will receive no credit (although I will go through
your answers with comments).
5b. There are no make-up exams. If you have a very good reason for
missing an exam you have to let me know beforehand or as soon as possible.
If I judge the
reason to be valid and you did let me know beforehand or ASAP, an alternative
will be available (probably in the form of an oral exam where I ask you
anything I
would have expected you to know on the exam).
6a. Students are most welcome to come in during office hours.
Generally if my office door is wide open even if not during my office hours, you're more than welcome to stop by. Remember, I'm here to help you master the material. On the rare instances I'm super-busy right when you appear, I'll just ask
you to come back a little later. I check my e-mail
reasonably
often during working hours so you can contact me that way too. (Don't
expect replies on weekends and evenings.)
6b. I love talking about the statistical thermodynamics and entropy and the strangeness of the universe we live in. So if you have a wild thought or idea, I'd
probably be interested in hearing it while giving you a dose of my wild ideas.
Hopefully that will be obvious from class!
7a. All students are expected to adhere strictly to the Academic Integrity
policy. Violations will be dealt with through the Dean of College of Arts
and Sciences, in
accordance with the University of San Diego policy on academic integrity.
7b. Use of an unauthorized solutions manual or one from previous years is considered a violation of academic integrity.
