Course detail

Chemical Thermodynamics and Kinetics in Material Engineering

FSI-BTKAcad. year: 2013/2014

The course deals with basic terms, principles and relations of classical chemical thermodynamics and kinetics, which are necessary to understand 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.Kinetics shows basic kinetic philosophy of physical-chemical processes in heterogeneous systems, particularly phase transformations diffusion and sintering.

Learning outcomes of the course unit

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

Prerequisites

Students are assumed to have secondary school knowledge of mathematics, physics, and chemistry.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures. Teaching is suplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

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 both tests with the result better than F. 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.

Aims

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.

Specification of controlled education, way of implementation and compensation for absences

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.
