Rate Of Reactions

• Factors affecting rate of reaction

  
  

  - Temperature

  - Concentration/Pressure

  - Catalyst

  - Surface Area.
• If the Temperature increases

  
  

  - Particles gains more energy

  - They move faster

  - There are more collisions

  - Activation energy can be reached
• Rate of Reaction = Amount of product/Time(s)
• Concentration/Pressure refers to how many particles per volume. Concentration refers to solutions and Pressure refers to gases.
• If the Concentration/Pressure increases

  
  

  - More particles

  - More collisions��
• If the Surface Area increases

  
  

  - High Surface area : Volume ratio

  - More collisions.
• If we use a catalyst

  
  

  - They speed up the reaction

  - Lowers Activation energy

  - Create an alternative reaction pathway
