COURSE OUTLINE

Objective: This objective of this course is to apply the fundamental concepts of thermodynamics developed in CHM 1381 (Physical Chemistry 1) to understand the physical properties of real chemical materials. Three basic categories of phenomena will be explored: (1) the phase behavior of pure and multiple chemical components, (2) properties of solutions, including colligative properties, and (3) the kinetics of chemical reactions. Examples will be included from industrial applications and biochemical systems where possible. A working knowledge of calculus (including multivariable calculus) and elementary differential equations is essential for this course.

Professor: David E. Budil

Textbook: K.J. Laidler and J.H. Meiser, Physical Chemistry, 3^rd edition, Houghton Mifflin Co.

(optional) Solutions Manual to Laidler&Meiser, Physical Chemistry, Houghton Mifflin (in

bookstore)

Grading: The final grade will be based on:

(1) The highest two scores from among the following:

(a) The total of the scores from four take-home assignments based on the study problems. (possible 100 pts).

(b) The score from each of two hourly tests. (possible 100 points each)

(2) A 2-hour final examination (possible 125 points).

A set of study problem sets will be assigned most Thursdays (not test weeks). Although the assigned problem sets will not be collected, it is highly recommended that you work through the homework assignments in preparation for the tests and take-home assignments. Solving problems is by far the best way to learn physical chemistry. The take-home assignments will be given out on Thursdays and due the following Monday. Late assignments will be accepted, but with a 5 point per day late penalty. Tests will be closed-book, but you are not expected to memorize equations: you will be allowed to bring in a 1-page summary sheet with relevant equations and physical constants.
