Collision Theory AQA Unit 2

HideShow resource information


  • Atoms needs to collide with sufficient energy to make or break bonds
  • The energy required to break and make these bonds is called the activation energy.
  • When particles collide, they need to exceed the activiation energy to react.
  • You don't say a particle is given activation energy, you say it is given the energy to  exceed the activation energy.
  • By increasing temperture you supply energy which means there's a greater proportion of successful collisions which succeed EA (activation energy)
  • Rate of reaction = change in concentration/ change in time
  • Rate of reaction = 1/time, if measuring how long it takes for a fixed constant amount
