PHASE EQUILIBRIA AND PHASE DIAGRAMS
(4 LECTURES, Problem set 1)
- Phase equilibria, phase diagrams, general concepts of one-component systems including H2O and CO2.
EQUILIBRIUM AND CHEMICAL THERMODYNAMICS
(8 LECTURES, Problem set 2)
- The equilibrium constant for physical and chemical changes, K in terms of activity.
- Thermochemistry and the first law of thermodynamics (energy, work); Hess’s law
