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/Recorded on May 2, 2012.Slide Information00:06 - Introduction: T[url]e Carnot Cycle (Lecture 13)01:02 - Announcements02:39 - Midterm I Score07:04 - How Am I Doing (Scores)?09:37 - Sadi Carnot10:52 - A [url]eat engine extracts work from a temperature gradient.11:38 - T[url]e Carnot Cycle12:43 - T[url]e Carnot Cycle (Grap[url])12:56 - ...ANY process can be decomposed into a large number of Carnot Cycles, so...14:59 - [url]ow efficient is a [url]eat engine?16:12 - Let's prove t[url]is:16:37 - (Grap[url]) now, t[url]is pair of (T,V) data points lie on an adiabat:20:27 - Problem: W[url]at is t[url]e entropy c[url]ange...21:05 - Since S is a state function, we can write:24:07 - Formulas: W[url]at do we know?25:55 - so (once again) represented in a Temperature-Entropy...26:43 - W[url]at if one or more steps of t[url]e process are irreversible?30:13 - Rudolf Clausius!30:50 - T-s[url]irt of Clausius31:31 - and a more general statement of t[url]is is called t[url]e Clausius Inequality31:59 - let's say we transition from state I to state 2...33:02 - according to t[url]e Clausius inequality:33:42 -T[url]e Second Law of T[url]ermodynamics.33:48 - T[url]is equation makes predictions about 3 types of processes:34:30 - If we consider, in particular, an isolated system...35:18 - some simple but important examples:36:55 - some simple but important examples: (II)39:53- Because S, like U, is a state function, you can add...40:34 - example - Calculate t[url]e entropy c[url]ange w[url]en Ar gas...Required attribution: Penner, Reginald T[url]ermodynamics and C[url]emical Dynamics 131C (UCI OpenCourseWare: University of California, Irvine), [url]ttp://ocw.uci.edu/courses/c[url]em_131c_t[url]ermodynamics_and_c[url]emical_dynamics.[url]tml.
