Factors effecting rate of reaction

• Increasing temperature 


  The particles will move faster causing a faster rate of reaction
• Concentration Increase 


  The particles are more crowded making the rate of reaction faster
• Larger surface area


  particles are more exposed and available for collisions - faster rate of reaction
• A Catalyst added

  increases the rate of reaction without being used up in the process
• Catalysts reduces the amount of energy needed for a successful collision
• Catalysts increase the number of effective collisions by providing an alternative pathway with lower activation energy
