Module 7 : Theories of Reaction Rates
Lecture 33 : Transition State Theory
 
   Objectives
   After studying this Lecture you will be able to do the following.

Distinguish between collision theory and transition state theory.
   

Obtain the rate constant in terms of an equilibrium constant of the transition state.

   
Express the transition state equilibrium constant in terms of the partition functions of the transition state and the
  reactants.
   
Associate the rate constant for the reaction {transition state products} with the vibrational frequency of the
  transition state.
   
Express the partition function of the transition state as a product of the partition functions for translational and
  other modes.
   
Define free energy, entropy and enthalpy of activation.
   
Rationalise the isotope effect on reaction rates.
