Physical Chemistry Lecture Notes

Thermodynamics, Electrochemistry, and Equilibrium

You will need the Adobe Acrobat Reader to view these files. This program is available over the InterNet or if you are on campus, from the General Server in the"Software for Use at Colby" folder. Most of the lecture notes have the same format: formula lines for the proofs but without the reasons for each step. Room is provided in the right-hand column for you to fill in with the reasons each step was taken. In this way you can concentrate on the flow of the proofs and the meaning of each formula and not worry about copying down each formula correctly for your notes.
