Subject aims expressed by acquired skills and competences
The aim of the course is to acquaint students with the basics of chemical thermodynamics and kinetics and their application to the technology of preparation of metallic materials.
Graduates of the course will know and understand the basic thermodynamic and kinetic concepts for the description of homogeneous and heterogeneous systems. They will be able to apply the basics of chemical thermodynamics and kinetics to selected technological processes and perceive these processes in a broader social context.
