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.
