  • 4.2- Collision Theory & Surface Area
    • Particles must collide with a certain amount of energy before they can react
    • The minimum amount of energy that particles must have in order to react is called the activation energy
    • The rate of a reaction increases if the surface area of any solid reactants is increased.
    • This increases the frequency of collisions between reacting particles
      • The rate of a reaction increases if the surface area of any solid reactants is increased.
