| 课程简介: | In Chemistry 131C, students will study how to calculate macroscopic chemical properties of systems. This course will build on the microscopic understanding (Chemical Physics) to reinforce and expand your understanding of the basic thermo-chemistry concepts from General Chemistry (Physical Chemistry.) We then go on to study how chemical reaction rates are measured and calculated from molecular properties. Topics covered include: Energy, entropy, and the thermodynamic potentials; Chemical equilibrium; and Chemical kinetics.Thermodynamics and Chemical Dynamics (Chem 131C) is part of OpenChem.This 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 18, 2012.Slide Information00:09 - Introduction: Integrated Law00:18 - today...00:41 - Two types of reactions: take for example the following:02:19 - stoichiometric03:12 - for elementary reactions...04:09 - this is another bimolecular reaction07:14 - How do we experimentally determine the rate law?17:48 - Method 3 - Use the integrated rate law to define the half-life of the reaction.20:30 - vs time for a 2nd order reaction...21:10 - Method 2: Use an integrated rate law.21:56 - we've mentioned 1st order and 2nd order reactions...zero order reaction.23:15 - [A] vs time for a 0 order reaction23:56 - what kind of reaction does this?24:36 - the microscopic view of "heterogeneous" catalysis26:00 - some common integrated rate laws.27:06 - so in reality, we have three methods for classifying a reaction...28:30 - Method 3.
