  1. 3.1 Collision Theory 3.1.1. Concentration and Collisions LO: I understand how the concentration affects the rate of a reaction.

  2. Collision theory states that substances can only react with each other if: (ii) The collision has enough energy. (i) The particles collide with each other and The the concentration of acid, the the number of collisions. higher greater higher The the number of collisions the the rate of reaction. greater LO: I understand how the concentration affects the rate of a reaction.

  3. 3.1.2 Particle Size and Collisions LO: I understand how the particle size affects the rate of a reaction

  4. surface Collisions can only take place on the of a solid. The greater the surface area the the number of collisions. greater The smaller the particle size the the surface area. greater LO: I understand how the particle size affects the rate of a reaction

  5. 3.1.3 Temperature and Collisions LO: I understand how the temperature affects the rate of a reaction.

  6. Increasing the temperature makes the particles: faster • move and collide more often • collide with more . energy The greater the temperature the the rate of the reaction. greater 10˚C In general, the rate doubles for every increase in temperature. LO: I understand how the temperature affects the rate of a reaction
