Course objectives
The course objective is to introduce students to a variety of chemical principles, in preparation for more detailed chemistry study in later years. Description of concepts and facts seeks the understanding of chemical world on an atomic and molecular level based on qualitative quantum theory. The molecular approach supports the comprehension of macroscopic phenomena and laws firmly depicted by thermodynamics and chemical kinetics.
