Physical Chemistry II

The subject provides theoretical and practical knowledge on the chapters of physical chemistry related to „change”. The rates of processes, as well as equilibrium electrochemistry are discussed. The three main chapters of physical chemistry II are Reaction Kinetics, Transport Processes and Electrochemistry.
