  1. 4.6.2.7 The effect of pressure changes on equilibrium (HT only)

Content

  • For gaseous reactions at equilibrium:
    • an increase in pressure causes the equilibrium position to shift towards the side with the smaller number of molecules as shown by the symbol equation for that reaction
    • a decrease in pressure causes the equilibrium position to shift towards the side with the larger number of molecules as shown by the symbol equation for that reaction.
    • Students should be able to interpret appropriate given data to predict the effect of pressure changes on given reactions at equilibrium.
