Description: In Chemistry 131C, students will study how to calculate macroscopic chemical properties of systems. This course will build on the microscopic understanding (Chemical Physics) to reinforce and expand your understanding of the basic thermo-chemistry concepts from General Chemistry (Physical Chemistry.) We then go on to study how chemical reaction rates are measured and calculated from molecular properties. Topics covered include: Energy, entropy, and the thermodynamic potentials; Chemical equilibrium; and Chemical kinetics.

This video is part of a 27-lecture undergraduate-level course titled "Thermodynamics and Chemical Dynamics" taught at UC Irvine by Professor Reginald M. Penner.

Very interesting commentary on the characteristic temperature and its relation to the partition function. One thing I find interesting is that the weird qv at the vibrational temperature (only 1.6) is purely a consequence of relying on the natural logarithm and e. Re-write statistical mechanics using a different base, and the numbers look very different (of course, Boltzmann's constant would be different too)!

But why we need more steps to reduce work
