This course is an introduction to chemical thermodynamics and its applications in geology. In addition to lecture and readings, there will be weekly homework assignments. Grades are based on 9 weekly homeworks, one midterm and a final project.
Part I, Basic Thermodynamics
Introduction to thermodynamics (definitions and basic concepts), the first law, heat, heat capacity and enthalpy.
Entropy and the second law of thermodynamics. Statistical interpretation of entropy and the third law.
Gibbs free energy and its pressure-temperature derivatives.
Fugacity, activity and chemical potential.
Part II, Phase Equilibrium
Gibbs phase rule and its modifications. Schreinemakers' geometric analysis, activity diagrams.
Thermodynamic data for rock-forming minerals. Solid-solid mineral equilibria.
Solid-melt equilibria.
Thermodynamics of gases.
Non-ideal mixing, Raoult's law, Henry's law
Solution chemistry: Eh, pH, the Debye-Huckle equation and applications.
