Unformatted text preview: Chem111 Fall, 2005 kinetics-1 Topic that deals with flux How fast do reactions occur? What influences how fast they occur? Experimental ! Kinetics also deals with reaction mechanisms to come soon elementary steps intermediate steps activated complexes and activation energy crucial concept = difference between kinetics and thermodynamics! Reaction Rates change in concentration (or partial pressure) with time depend on 4 things 1. Nature of the reactants and the type of reaction 2. Concentrations (partial pressures) of molecules involved, including both the reactants and products 3. Temperature 4. Presence of a catalyst Lecture 22: Kinetics Introduction Differential rate laws Integrated rate laws Chem111 Fall, 2005 kinetics-2 1. Nature of the reactants and the type of reaction physical state of the reactants type of reaction (one down three to go! The next one is a BIG one though!) Chem111 Fall, 2005 kinetics-3 2. Concentrations (partial pressures) of molecules involved, including both the reactants and products...
