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 16, 2012.00:06 - Introduction: Observational chemical kinetics00:17 - Henry Louis Chatelier (1850 - 1936)00:25 - Henry Lous Chatelier..."I let the discovery of the ammonia sythesis slip..."02:21 - Le Chatelier's Principle says, for example, that with an increase in the total...02:47 - example: Can we determine the relationship between...03:06 - answer:06:30 - what about the influence of temperature on K?08:12 - That's it for Thermodynamics (Topic discussed in Chapter 17)10:11 - Diagram: where are we?12:30 - the first chemical subjected to kinetic analysis?13:12 - some notation&jargon...a stoichiometric reaction...17:30 - so an elementary reaction is one in which the indicated products...17:53 - we discussed the extent of reaction...18:52 - this is not as confusing as it looks. Here's an example...20:19 - in terms of the extent of reaction...22:44 - ...for this generation reaction...23:20 - in terms of the extent of reaction...23:30 - A rate law relates the concentration of reactants...28:23 - for stoichiometric reactions, the rate law can not be deduced by inspection.30:08 - Often, reactions are significantly reversible and both the forward and backward...32:10 - be reminded that these simple expressions apply only because...33:35 - what are the units of the rate constant in this case?34:46 - Method 1. Method of Initial Rates40:05 - Method 2. Use an integrated rate law.43:59 - Method 2. (continued) Half-life45:17 - Graph: (length of half of line is constant.)45:55 - How do we experimentally determine the rate of lawFor more information and access to courses, lectures, and teaching material, please visit the official UC Irvine OpenCourseWare website at: http://www.ocw.uci.edu
