Chemical Concepts, Systems and Practices II
Instructor(s): Lewis Rothberg, Kara L. Bren, Thomas R. Krugh

Prerequisites: CHM 131 or equivalent.
Crosslisting: None.

Course Summary:
A continuation of Chemical Concepts, Systems and Practices I, emphasizing molecular and macroscopic approaches to chemical systems with examples concerned with life sciences or energy and the environment. Topics covered include: Chemical kinetics, electrochemistry, thermodynamics, properties of atoms, atomic structure, and chemical bonding. In addition to course lectures, there is a three hour laboratory every week, a 50 minute laboratory/lecture and a 50 minute recitation. You must register for the laboratory/lecture and laboratory (linked) prior to the start of the semester. Recitations will be assigned in the main lecture during the first week of classes. This course uses the Tuesday/Thursday 8:00 - 9:30 am Common Exam time.
