Temperature

• How does increasing temperature increase the rate of reaction?


  Warmer environment means the particles move quicker and more energy is transferred

  These particles collide more often with greater energy

  So more collisions occur frequently and successfully
• What is the independent variable of the rate of reaction temperature investigation?

  The temperature of the acid
• What is the dependent variable of the rate of reaction temperature investigation?

  How much gas is produced at set time intervals
• What are the control variables of the rate of reaction temperature investigation?

  -volume of acid

  -concentration of acid

  -surface area of acid
• Name the equipment

  gas syringe

  
• Name the equipment

  Conical flask

  
• What happens to the rate of reaction when the temperature is increased?


  At a high temperature, the particles move faster

  Particles collide more often and with more energy
• Use the diagram to describe what happens to the particles in a substance when its temperature is increased


  The higher the temperature, the particles move fast and so they collide more often with more energy
