Learning outcomes of the course unit
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 receive the information on fundamental physico-chemical properties of disperse colloidal systems, as well as on properties of surfaces. The obtained knowledge the students verify in the frame of calculations, which passing in the form of credit is the condition for the acceptance to the oral exam from the subject Physical Chemistry II. The performance of the exam is the base for the consecutive succesfull passing of futher subjects, namely Chemical engineering.
Knowledge from selected chapters of Physics I., II. (state of matter, electrodynamics, optics). Basic knowledge of differentiation and integration.
