  • increasing the concentration or pressure
  • means there are more reactant particles
  • increasing the concentration or pressure
    • means there are more reacting particles
    • greater chance of particles colliding
    • the rate of reaction increases
  • greater chance of particles colliding
  • surface area has increased
  • when the temperature is increased
    • particles move quicker (more energy)
    • collide more
  • what does a catalyst do?
    • lowers activation energy
      • which means more collisions result in a reaction
        • rate of reaction increases
