Within the part Chemical kinetics the students obtain the basic knowledge on kinetics of elementary and complex reactions, on kinetics of homogeneously and heterogeneously catalyzed reactions and on factors, influencing the reaction rate. Within the part Colloidal chemistry students obtain the information on fundamental physico-chemical properties of disperse colloidal systems, as well as on properties of surfaces.

Knowledge from selected chapters of Physics I., II. (state of matter, electrodynamics, optics). Basic knowledge of differentiation and integration

Not applicable.
