Learning outcomes of the course unit

Completing the course, students should obtain more complex view on problems of chemical kinetics. Finishing the studies at the Faculty, they should be able to solve the problems in the field of chemical kinetics in laboratory or industrial practice.

Prerequisites

Basic knowledge from chemical kinetics, obtained within the subject Physical chemistry II., Basic knowledge of differentiation and integration.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Aims

The goal of the subject is the improvement of knowledge of basic course of chemical kinetics, presented within Physical Chemistry II. Students are aquainted with the kinetic analysis of reactions, which is in comparison with basic course substantially more sophisticated from mathematical point of view.
