The goal of the subject Physical chemistry I. is to provide the students with the rudiments of chemical thermodynamics and electrochemistry in such a way, that the students are able to utilize them by the solution of problems in laboratory and industrial practice. Simultaneously, the obtained knowledge serves as a basis for the study of other subjects.
