Professor Sylvia Ceyer discusses the effects of temperature on reaction rates, including in her lecture the Arrhenius equation, activation energy, reaction coordinate, and the activation complex.

Within a lecture on biological resolution, the synthesis of single enantiomers, and the naming and 3D visualization of omeprazole, Professor Laurence Barron of the University of Glasgow delivers a guest lecture on the subject of how chiral molecules rotate polarized light. Mixing wave functions by coordinated application of light's perpendicular electric and magnetic fields shifts electrons along a helix that can be right- or left-handed, ...more

Ringold talks about the idea behind and the history of combinatorial chemistry to accelerate the process of drug discovery. He then talks about a technology that was invented for a different purpose but was eventually applied to the specific problem of broadly monitoring the expression of gene sequences giving birth to Affymetrix.

Professor Sylvia Ceyer investigates chemical reaction mechanisms: rate, order, molecularity, steady-state approximation, and rate determing steps.
-
Professor Sylvia Ceyer introduces transition metals and the formation of coordination complexes. The Chelate effect is defined and the difference between geometric isomers and optical isomer (enantiomers) is discussed. The discussion concludes with d orbitals and d-electron counting in coordination complexes.
-
Professor Sylvia Ceyer explains the standard Gibbs free energy of formation and its relationship to thermodynamic stability. The Second Law of Thermodynamics is defined as it relates to controlling spontaneity with temperature. The lecture concludes by defining the thermodynamic equilibrium constant and the reaction quotient/direction of change in a chemical equilibrium.

Professor Sylvia Ceyer covers radioactive decay and its various uses in modern medicine. Second order half-life, as a second order integrated rate law, is then discussed. The lecture concludes with the overlap of kinetics and chemical equilibrium: the equilibrium constant, elementary reactions, and an example, the decomposition of ozone.
