Catalysts

• Catalyst


  Catalysts increase the rate of chemical reactions but are not used up during the reaction
• Catalysts


  • They allow us to carry out reactions quickly without needing to increase the temperature
  • They can be reused again and again
• Activation energy


  The minimum amount of energy that the particles must have in order to react
• How catalysts work


  1. Catalysts provide a different pathway for the reaction that has a lower activation energy

  2. This means more particles can successfully collide per second, increasing the rate of the reaction
• Catalysts are not included in the chemical equation for a reaction
• Different reactions need different catalysts
• Enzymes act as catalysts in living organisms
