1. Formal chemical kinetics: Concepts, simple and simultaneous reactions.

2. Reaction mechanisms, catalysis, enzyme kinetics (Michaelis–Menten), inhibition.

3. Equilibrium thermodynamics: Gibbs and Helmholtz functions, activity, chemical potential. Chemical equilibria, the direction of chemical reaction, simultaneous reactions.

4. Chemical equilibria in aqueuous solutions: pH, weak acids and bases and their salts, buffers, slightly soluble salts.

5. Statistical thermodynamics light: Pressure of ideal gas and the interpretation of temperature, Boltzmann probability, entropy.

6. Electrostatic phenomena in ionic solutions: Debye-Hückel theory, electrical double layer.

7. Electrochemistry: Galvanic cells, Nernst equation.

8. Thermodynamics of mixtures: Colligative properties, osmotic pressure.

9. Nonequilibrium thermodynamics: Transport properties, Fick's laws, diffusivity, electrical conductivity.

10. Interfaces: Surface and interface tension, wetting. Curved interfaces, nucleation.

11. Adsorption: Surface excess and Gibbs adsorption isotherm. Adsorption isotherms and models (Freundlich, Langmuir, BET).

12. Dispersion systems - classification: Colloid, sol, gel, foam, emulsion, aerosol; solutions of macromolecules; micelles, surface films. Rheology, optical properties.

13. Dispersion systems - phenomena: Forces between colloidal particles. Sedimentation, electrokinetic phenomena, zeta potential.
