Collision Theory

Collision theory explains how reactions happen and why they happen at different rates.

Particle collisions

  • Particles must collide for chemical reactions to happen.
  • Importantly, these collisions must happen with enough energy.
    • This minimum amount of energy is known as the activation energy.

Rate of reaction

  • We can increase the rate of a reaction by increasing the frequency (number) of collisions and/or the energy of reactant particles.
  • This can be achieved by changing lots of different factors.
