Not applicable.

Students will acquire basic knowledge of classical chemical thermodynamics and kinetics, and will understand their logic and how to apply them to solving engineering tasks. They will learn to use literature sources and databases.

Students are assumed to have secondary school knowledge of mathematics, physics, and chemistry (general, inorganic and organic chemistry).

Not applicable.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Course-unit credit requirements: attendance at seminars and passing a written test. There will be two written tests during the semester. Students are required to pass one of the tests with the result better than D. The assistant determines dates of re-sit tests. Examination verifies the knowledge of the theory and particularly its application. It contains written and oral parts. Examiner may modify the relative importance of oral and written parts of the exam, he/she can take student’s activity during the semester into account. The examiner has to familiarize students (at the latest during the last lecture) with the course of examination and with the principles of evaluation.

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 to understand physical-chemical problems of material science, and to teach them how to apply them.

Attendance at all practical lessons and fulfilment of assignments is required. In case students do not meet these conditions they can be given additional assignments.
