Chapter 8 · Collision theory and rates

Chapter 8 recap

  • Successful collision = correct orientation + at least the activation energy
  • Rate = successful collisions per unit time: measure a change and time it
  • Higher concentration, surface area or temperature → faster. A catalyst speeds it up without being used up
  • Next: Chapter 9 · Rate graphs and experiments
