WebLecture: Reaction Mechanisms

Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 14: Sections 5-6.

  1. 14.5 For a reaction to occur, the reacting molecules molecules must not only have sufficient kinetic energy of motion (activation energy Ea), they must also collide effectively. The rate of a reaction depends not only on temperature, where heat energy supplies the kinetic energy for the collision, but on the shape of the molecules, and the frequency of effective collisions.
  2. 14.6 A reaction mechanism may involve multiple reactions between initial reactants and their intermediate products to produce the final products of the overall reaction. The rate of a multiple-step reaction will be constrained to the rate of the slowest reaction step.
