The flashcards below were created by user DesLee26 on FreezingBlue Flashcards. What would you like to do?


  1. what determines the value of hte rate constant?
    collision energy x collision frequency x collision orientation
  2. Explain collision frequency.
    • tempĀ 
    • concentration (for gas, increase P, decrease volume)
  3. Explain collision energy
    molecular weight and temp
  4. Explain Collision orientation
    directionality
  5. Typically, as the temperature increases, what happens to the rate
    it increases
  6. True or False:
    The rate constant is independent of the temperature.
    • False
    • dependent
  7. Collision theory
    As the average kinetic energy increases, the average molecular speed increases, and thus the collision frequency increases as well as the energy of collisions
  8. transition state
    The configuration of atoms at the maximum in the potential energy profile. This is also called the activated complex
  9. If the catalyst is involved in the rate determining step, what?
    it will appear in the rate law
