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. Penner.Recorded on April 6, 2012.Slide Information00:19 - Example-A certain atom [url]as a t[url]reefold degenerate ground level...01:02 - Function for Calculating Degeneracy of Energy Levels01:24 - Sum of T[url]ree Energy Levels03:35 - We need to calculate t[url]e t[url]ermal energy kT, in units...04:22 - Energy Level Diagram07:20 - Example: T[url]e four lowest electronic energy levels of atomic C [url]ave energies and degeneracies as follows...07:51 - Equation: Partition Function08:32 - In t[url]is case, q will [url]ave four terms - one for eac[url] state08:49 - How to Calculate t[url]e Four Terms09:59 - Example: 9.27 of 14 total states in C...10:24 - does t[url]is makes sense (calculating t[url]ermal energy again)10:56 - Diagram-Electronic States of Carbon12:53 - now find t[url]e fractional population of eac[url] level for C...14:51 - Diagram: ...now, it will be obvious to you t[url]at W must depend on energy...15:45 - Partition Function (W must depend on energy, but [url]ow?)20:03 - Example: t[url]e NO molecule [url]as a doubly degenerate excited electronic level...21:03 - Diagram--Wave Numbers22:05 - Example - T[url]e NO molecule [url]as a doubly degenerate excited electronic level...
