Collision Theory

    Cards (8)

    • What happens to the rate of chemical reactions over time?
      • Reactions are rapid initially
      • Over time, reactions slow down
      • Finally, reactions stop
    • What is collision theory?
      Collision theory states that chemical reactions can only occur when reacting particles collide with sufficient energy
    • What determines the rate of a chemical reaction according to collision theory?
      The frequency of successful collisions
    • What does the term 'frequency' refer to in the context of chemical reactions?
      The number of successful collisions per second
    • What happens to the reaction when all reactant molecules have run out?
      The reaction stops
    • What is the basis of collision theory in chemical reactions?
      Chemical reactions occur when reacting particles collide with sufficient energy
    • How is the rate of a chemical reaction determined?
      By the frequency of successful collisions
    • What does the term frequency refer to in the context of chemical reactions?
      The number of successful collisions per second
