Description

Thermodynamics and Chemical Dynamics (Chem 131C) is part of OpenChem: http://learn.uci.edu/openchemThis video is part of a 27-lecture undergraduate-level course titled "Thermodynamics and Chemical Dynamics" taught at UC Irvine by Professor Reginald M. Penner.Recorded on May 9, 2012.Slide Information00:05 - Announcements:01:41 - Today:02:40 - The Chemical Potential02:50 - ...from last Monday, and last Friday:03:48 - useful | more useful04:49 - Graph (What does...)06:28 - How does G depend on temperature?08:28 - The third law of thermodynamics...09:50 - Graph10:32 - We usually consider the temp. dependence of...11:26 - This bad boy is called the Gibbs-Helmholtz Eq.12:09 - This bad boy...(cont)12:43 - Ok, now how does G depend on pressure...13:54 - but, for phases, like solids and liquids, that are essentially...14:17 - For ideal gases:14:47 - conclusion: Gibbs energies of solids and liquids...15:40 - The T-dependence of the Gibbs function:17:31 - Now, as we transition (however briefly) into...18:06 - How do individual reactant and product species...18:17 - Matter matters: How is G affected by transfers...18:45 - we haven't said much about open systems that exchange matter:18:54 - consider the mixing of two isotopes of hydrogen (experiment)21:10 - since G is an extensive variable22:09 - we understand the T and P dependencies of G already...23:57 - we know, after we open the valve, the isotopes will...26:06 - combining these statements allows us to express...28:05 - so with the valve open, mixing stops when...29:33 - The partial molar Gibbs free energy is to..33:34 - the partial molar Gibbs free energy (cont)32:44 - The figure from your book really helps...34:54 - the partial molar Gibbs free energy is too important39:38 - exercise 16.4b: A mixture of ethanol and water is prepared...42:34 - Now, we already understand that G is minimized upon an approach to equilibrium...42:39 - In other words...44:00 - This is called the Gibbs-Duhem Eq.44:57 - Graph: This permits an understanding of thermal phase transactions:45:36 - We already know how this works for, say, water:49:13 - "the system "selects" the phase of lowest..."49:24 - now, before we go further, let's clear up some mystery...For more information and access to courses, lectures, and teaching material, please visit the official UC Irvine OpenCourseWare website at: http://www.ocw.uci.edu
