Effect of temperature on reaction rate

• What effect does increasing temperature have on the rate of reaction?

  It increases the rate of reaction
• How does temperature increase the rate of reaction?

  • Particles move faster at higher temperatures
  • More frequent collisions occur
  • Higher number of successful collisions
  • Higher proportion of molecules have activation energy
• Why do particles collide more frequently at higher temperatures?

  Because they are moving faster
• What is the relationship between the number of collisions and successful collisions at higher temperatures?

  More collisions lead to more successful collisions
• What happens to the proportion of molecules with activation energy at higher temperatures?

  It increases
• How does a higher proportion of successful collisions affect the reaction rate?

  It increases the reaction rate
• What happens to the number of collisions when the temperature is increased?

  It increases and the proportion of successful collisions increases
