Factors which affect RRR

    Cards (7)

    • State the factors which affect the rate of reaction:
      1. Temperature
      2. Concentration/ Pressure
      3. surface area
      4. Catalyst
    • What effect does increasing the concentration of a solution have on the rate of reaction?
      It increases the rate of reaction
    • Why does increasing pressure of gases affect the rate of reaction?
      It brings particles closer together
    • How does increasing the surface area to volume ratio affect the rate of reaction?

      It increases the frequency of collisions
    • What happens to particle movement at cold temperatures?
      Particles move slower
    • How does temperature affect the frequency of collisions in a reaction?
      Higher temperature increases collision frequency
    • What are the effects of increased temperature on the energy of particles in a reaction?
      Particles have more energy and collide more
