Chemsitry Seminar with Dr. Gregory Yablonsky

Please join us for Dr. Yablonsky's seminar, titled "TIME: THE MAIN MYSTERY OF CHEMICAL KINETICS"

Abstract

Time as the main theoretical concept of chemical kinetics is analyzed with a focus on reactions of heterogeneous catalysis. Under steady-state conditions, the reciprocal reaction rate (normalized) is presented as the intrinsic reaction time. This time is termed as the ‘kinetic resistance”. Different constituents of the new kinetic paradigm for decoding chemical complexity are presented: 1. Analysis of relaxations and critical phenomena. 2. Eliminating time based on the temporal hierarchy. 3. Controlled catalyst change via pulse-response methods. 4. Joint Kinetics, i.e. new kinetico-thermodynamic invariances found via combinations of different experiments. Trends and events in chemical kinetics are categorized and analyzed. Theoretical achievements are illustrated by examples of catalytic oxidation and reforming reactions.
