Collision theory

• What is the definition of collision theory?

  Particles must collide with sufficient energy
• What is required for a reaction to occur according to collision theory?

  Correct orientation and sufficient energy
• What are the key factors affecting reaction rates in collision theory?

  • Frequency of collisions
  • Energy of collisions
  • Concentration of particles
• How does the frequency of collisions affect reaction rates?

  More collisions lead to faster reactions
• What must particles do to overcome the activation energy barrier?

  They need enough energy during collisions
• How does concentration affect the number of collisions?

  Higher concentration results in more collisions
• What happens at low concentration in terms of collisions?

  There are few collisions
• What happens at high concentration in terms of collisions?

  There are more collisions
