Chemical Thermodynamics and Kinetics (FSI-WCT)

Academic year 2020/2021
Supervisor: prof. RNDr. Karel Maca, Dr.  
Supervising institute: ÚMVI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
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.
Learning outcomes and competences:
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.
Prerequisites:
Student has to have high-school knowledge of mathematics and physics, and chemistry (general, inorganic and organic chemistry).
Course contents:
Course deals with basic terms, principles and relations of classical chemical thermodynamics and kinetics, which are necessary for understanding of physical-chemical problems of material science. Chemical thermodynamics is focused on basic thermodynamic principles, variables and relations, description of equilibrium in single- and multi-component homogenous and heterogeneous systems, and on phase diagrams. Multi-component chemical reactive systems and problem of capillarity are also mentioned.
Kinetics shows basic kinetic philosophy of physical-chemical processes in heterogeneous systems, particularly phase transformations diffusion and sintering.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by theoretical exercises and also by practical laboratory work.
Assesment methods and criteria linked to learning outcomes:
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 contains written and oral parts. Examiner assesses the relative importance of oral and written parts of the exam, he 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
Controlled participation in lessons:
Attendance at all practical lessons and fulfilment of assignments are required. In case that students do not meet these conditions they can be given additional assignments.
