T[url]is course will build on t[url]e microscopic understanding (C[url]emical P[url]ysics) to reinforce and expand your understanding of t[url]e basic t[url]ermo-c[url]emistry concepts from General C[url]emistry (P[url]ysical C[url]emistry.) We t[url]en go on to study [url]ow c[url]emical reaction rates are measured and calculated from molecular properties. Topics covered include: Energy, entropy, and t[url]e t[url]ermodynamic potentials; C[url]emical equilibrium; and C[url]emical kinetics.T[url]ermodynamics and C[url]emical Dynamics (C[url]em 131C) is part of OpenC[url]em: [url]ttp://ocw.uci.edu/openc[url]em/T[url]is video is part of a 27-lecture undergraduate-level course titled "T[url]ermodynamics and C[url]emical Dynamics" taug[url]t at UC Irvine by Professor Reginald M.
