Course objectives

The aims of the course are to enable students to:
- understand chemical and electrochemical kinetics which is raised at a higher level,
- understand processes and equilibriums in electrolyte solutions, and understand of surface dynamics,
- resolve different physicochemical problems,
- apply acquired knowledge and skills in professional and specialist courses.

Course enrolment requirements and entry competences required for the course
