Chemical Thermodynamics and Kinetics (FSI-WCT)

The objective of the course is to inform students about selected basic terms, principles and relations of classical chemical thermodynamic and kinetic, which are necessary for understanding of physical-chemical problems of material science, and to teach the students how to apply them. Another, by no means negligible task, is to develop students' logical and abstract thinking.
Students will obtain basic knowledge of classical chemical thermodynamics and kinetics of selected engineering processes, and will understand their logic and how to apply them for solution of engineering tasks aided by literature sources and databases.

Student needs knowledge of mathematics and physics at the level of the first two years of study of FME, and at least high-school knowledge of chemistry (general, inorganic and organic chemistry).

Conditions of credit landing are presence in practical lessons and written tests.
There will be two written tests during the semester. Student has to be classified better than F at both tests. The assistant determines dates of corrective tests.
Examination verifies the knowledge of the theory and particularly its application. It is oral. Examiner can take into account student’s activity during the semester. The examiner has to familiarize students (at the latest during the last lecture) with the course of examination and with the principles of classification
