Academic year:

2019/2020.

Attendance requirements:

103H1 / 103P1

ECTS:

8

Study level:

Study programs:

Teacher:

Maja T. Šumar Ristović, Ph.D.
associate professor, Faculty of Chemistry, Studentski trg 12-16, Beograd

Assistant:

Teodora S. Vitomirov
teaching assistant, Faculty of Chemistry, Studentski trg 12-16, Beograd

Hours of instruction:

Weekly: four hours of lectures + four hours of labwork (4+0+4)

Goals:

The interpretation of modern concepts of inorganic reaction mechanisms helps students consolidate and integrate their knowledge. The organization of the course encourages students to use individual approach in solving some problems.

Outcome:

Integrated theoretical and applied knowledge of the structure, chemical bonds and free energy of all substances in a reaction provides an excellent base for students to build on and expand their knowledge.

Teaching methods:

The course includes lectures, experimental practical classes with theoretical foundations, calculation exercises and public presentation (Power Point) of the results. The teacher uses interactive approach in the lectures. The practical classes are based on the principles of research/problem-solving learning with detailed kinetic calculations and simulations of mechanisms. Students are also instructed on how to search for information using scientific databases and how to present the result of their work.

Extracurricular activities:

Students study the theoretical material needed for practical classes at home and collect data from the available literature.
