Chemical kinetics

• What is rate of reaction measured in?

  Mol dm^-3 s^-1
• What are the three factors for successful collision?

  Proper orientation, sufficient energy, and effective collision frequency.
• What five factors affect rate of reaction?

  Temperature, concentration, surface area, catalysts and pressure
• How does a catalyst work?

  It lowers activation energy by providing an alternative pathway
• How does temperature affect rate of reaction?

  Many more molecules now have a higher energy than the activation energy so there are more frequent successful collisions per unit of time
