Subject aims expressed by acquired skills and competences

- to use of the kinetic equations for first-order chemical reactions, second-order reactions and reactions of higher orders, - to describe and analyse the reaction mechanism based on the kinetic data, - to describe and qualified estimate kinetic parameters of chemical reactions.

Teaching methods

Individual consultations


The topic of the subject is a theoretical basis in the area of application of physical chemistry principles to particular heterogeneous reactions. Chapters selection will be made regarding the topic of the dissertation thesis and together with the supervisor.
