1. Chemical thermodynamics: chemical equilibrium, influences on the state of chemical equilibrium, reaction enthalpy, reaction entropy, Gibbs free reaction energy. 2. Electrochemistry: participation of electrically charged particles in the chemical equilibrium and chemical reactions, electro-chemical cells, structure of electrolyte solutions, ideal and real electrolyte solutions, mechanisms of electric conductance in solid and liquid phase. 3. Quantum mechanics in chemistry: Schrödinger equation, electronic structure in atoms (periodic table), molecules and solids, covalent chemical bond 4. Participation of photons in the chemical equilibrium and in chemical/physical reactions, general fundamentals of spectroscopies, application of atomic and molecular spectroscopy. 5. Statistical thermodynamics: Boltzmann-, Fermi-Dirac-, and Bose-Einstein statistics, determination of thermodynamic state functions via quantum-chemical calculations.
