  The formation of n2o4 from no2
• What type of reaction is the forward reaction in the discussed reaction?

  Exothermic
• What happens to energy during the forward reaction?

  Energy is released
• What is the nature of the reverse reaction in this case?

  Endothermic
• What occurs when the reverse reaction takes place?

  Energy is taken in
• What happens to the equilibrium if the temperature is increased?

  The equilibrium shifts to the left
• Why does the equilibrium shift to the left when temperature increases?

  To reduce the temperature
• What happens to the amount of no2 when temperature increases?

  It increases
• What happens to the amount of n2o4 when temperature increases?

  It decreases
• What happens to the equilibrium if the temperature is decreased?

  The equilibrium shifts to the right
• Why does the equilibrium shift to the right when temperature decreases?

  To increase the temperature
• What happens to the amount of n2o4 when temperature decreases?

  It increases
• What happens to the amount of no2 when temperature decreases?

  It decreases
• What are the effects of changing temperature on reversible reactions at equilibrium?

  • Increasing temperature shifts equilibrium left
  • Decreasing temperature shifts equilibrium right
  • Forward reaction is exothermic; reverse is endothermic
