Transition state theory

• What does transition state theory assume?

  A quasi-equilibrium between reactants and the activated complex
• what do both collision theory and transition state theory predict?

  a temperature dependence to A
• what must be the enthalpy of a transition state?

  positive
• what does large values of A in the Arrhenius equation tells us about entropy?

  positive, very ordered compared to reactant
• what does a small value of A in the Arrhenius equation tells us about entropy?


  Negative
• Comparing Gibbs energy between multiple transition states tells us?

  speed that intermediate is formed.

  • smaller gibbs the quicker intermediate is formed
