Learning Outcomes

Upon successful completion of this course the students will acquire new knowledge and specific skills on the following subjects and will be able:

  1. To understand in depth issues related to the kinetics and rate of homogeneous and heterogeneous chemical reactions and their mechanisms.
  2. To conduct experiments to obtain kinetic equations and to analyze them in order to understand the mechanism of homogeneous and heterogeneous reactions.
  3. To construct/develop reaction mechanisms based on experimental evidences and vice versa to derive kinetic equations based on the mechanisms of reactions.
  4. To understand in depth electrodic phenomena, electrochemical reactions, and the operation of electrochemical devices of any type (batteries, fuel cells, electrolytic cells). To know the basic equations which govern the behavior of electrochemical cells and to analyze their operation.
