No lecture
Brush-up of your knowledge of statistical
thermodynamics, especially the basics of
microcanonical ensemble, calculation of the molecular canonical partition
function and the calculation of the equilibrium constant from the canonical
partition function.
To learn: your notes, and
The statistical thermodynamics Chapter of the
textbook Chemical Thermodynamics.
Auxiliary material:
The presentation shown in class of statistical
thermodynamics summary. The thermodynamics
textbook of H. B. Callen.
Thursday March 6
Theories of elementary reactions
based on statistical physics: Collision theory, Potential Energy Surfaces (PES)
and the Transition State Theory (TST) based on the quasi-equilibrium
approximation. TST based on a dynamic approximation on a PES, and
quantum dynamical simulations without invoking the Born-Oppenheimer
approximation and PES.
To learn: your notes, Chapters 1 and 2 (pp. 1-37) of the Textbook; a
booklet on rate theories (or pages 1-25
of the
Hungarian kinetics notes), and Chapter 3 of the
Pilling book / its
Hungarian edition.
Auxiliary material:
The presentation shown in class.
A historical overview of the development of theories can
be found in Hungarian in MKL p. 368, in
English in the manuscript sent to Polanyiana.
Thursday March 13
Experimental methods used to study chemical
kinetics: "classical" methods, discharge flow, continuous flow and stopped flow
reactors, relaxation methods. Methods of detection: resonance fluorescence,
laser induced fluorscence, mass spectrometry. Shock tubes. Flash photolysis and
laser photolysis.
To learn: your notes, the presentation
shown in class, Chapter 7 (pp. 161-181) of the Textbook;
and Chapter 2 of the
Pilling book / its
Hungarian edition. A booklet on
elementary kinetics, where the last pages discuss pseudo-first-order
reactions in more details (or pages 39-41 of the
Hungarian kinetics notes).
Thursday March 20
Reaction dynamics: Interaction potentials and the harpoon
mechanism. Early experimental methods: large experimental setups for molecular
beam collisions. Recent experimental setups: laser beams and their interaction
with bulk mixtures and molecular beams. State-selective excitation and
state-selective detection.
To learn:
your notes, a
booklet on rate theories (or pages 1-25
of the
Hungarian kinetics notes), and Chapter 4 of the
Pilling book / its
Hungarian edition.

Thursday April 10
Guest speaker: András Szanthoffer
Topics:

To learn: Chapter 5 of the
Pilling book / its
Hungarian edition + your notes.
Auxiliary material:

Maundy Thursday; No lecture
Kinetics of reactions in solution: General considerations
concerning the difference between condensed phase reactions and gas phase
reactions. Electrostatic interactions of ions and dipole molecules and their
contributions to the energetics of reactions. The effect of activity on the rate
of reactions ("primary salt effect").
To learn: your notes and Chapter 6 of the
Pilling book /
its Hungarian edition.
