While Physical Chemistry I explained phenomena by the postulates of classical thermodynamics and the ideas of matter as a continuum, in the Physical Chemistry of Microcosm we explain phenomena based on the atomic theory represented mainly by the statistical thermodynamics and kinetic theory. This view is indispensable for understanding nano and microobjects as well as polymers. A part of the lecture is devoted to expanding knowledge of classical physical chemistry (kinetics, chemical equilibria).
Aim of the course -
