The spontaneous nature of chemical reactions. Gibbs energy and its variation. The chemical potential. The ideal solutions. Equilibrium reaction: thermodynamic fundamentals. The response of equilibrium under pressure and temperature.
Chemical kinetics: the reaction rate, its definition and measurement. Kinetic laws, rate constants and reaction orders. Methods for the determination of the kinetic law. Zero, first and second order reaction. The dependence of the reaction rate on temperature. The Arrhenius equation. Interpretation of the Arrhenius parameters. Thermodynamics and kinetics of protein folding.
Laboratory of analytical techniques
Basic analytical principles. Titrations. Electroanalytical techniques and potentiometric pH monitoring. Spectroscopic techniques (UV-vis, fluorimetry, polarimetry, IR). Chromatographic separation techniques (TLC, GC, HPLC)
Nuclear Magnetic Resonance spectroscopy: basic principles of the NMR experiments. Spectral parameters: chemical shift and coupling constants. One-dimensional 1H-NMR experiments. The nuclear Overhauser effect: theoretical background.
Mass Spectrometry: Instrumentation and recording of spectra. Ionization methods. Key fragmentation reactions in organic compounds. Examples and applications.

The written examination consists of a series of questions (open and multiple choice) and exercises. The questions cover the entire subject of the course. Available time: two hours.
