Overview
This is the first part of a 2-semester course in thermodynamics. This course will cover the mathematical theory of chemical equilibrium, heat, and work. These are the driving forces behind the operation of Le Châtelier's principle, and are routinely used to understand and control chemical reactions, states of matter, and amount and efficiency of energy production.

Textbooks

 * McQuarrie and Simon, Physical Chemistry: A Molecular Approach, University Science Books, 1997. ISBN: 0935702997.

Resources

 * Kinetic Theory at HyperPhysics
 * Heat Concepts at HyperPhysics
 * Note: McQuarrie says dU = dQ + dW, while Nave says dU = dQ - dW. There is no contradiction, since McQuarrie's dW = -P dV (work done on the system), while Nave's dW = P dV (work done by the system).  I prefer the first definition.
