Open Yale CoursesCHEM 125: Freshman Organic ChemistryLecture 37 - Potential Energy Surfaces, Transition State Theoryand Reaction Mechanism<< previous session| next session >>Overview:After discussing the statistical basis of the law of mass action, the lecture turns to developing a framework forunderstanding reaction rates. A potential energy surface that associates energy with polyatomic geometry canbe realized physically for a linear, triatomic system, but it is more practical to use collective energies forstarting material, transition state, and product, together with Eyring theory, to predict rates. Free-radical chainhalogenation provides examples of predicting reaction equilibria and rates from bond dissociation energies.The lecture concludes with a summary of the semester's topics from the perspective of physical-organicchemistry.Problem sets/Reading assignment:Reading assignments, problem sets, PowerPoint presentations, and other resources for this lecture can be
