The unit aims to provide students with in-depth knowledge of the basic concepts and approaches in chemical kinetics, as well as basic knowledge of the application of kinetic laws in the description of chemical reactors. Topics: reactions in solutions; adsorption and reactions on a surface; homogeneous and heterogeneous catalysis; influence of mass and heat transfer on the rate of chemical reactions; kinetics in chemical reactors. In all sections, specific examples are given to illustrate the basic patterns and their applications, and relevant experimental methods are discussed.
