Chem1 Virtual Textbook - Real Gases
Great discussion of real gases and the Van der Waals equation of state. Some of the discussion of supercritical fluids may be a bit advanced, but it is well worth the attention.

Purdue University - Deviations from Ideal Gas Law Behavior
Comprehensive presenation of the Van der Waals equation. For the MCAT, pay close attention to the conceptual side to this topic. Quantitative problem solving with the Van der Waals equation is not a traditional emphasis on the MCAT.
