5.6.2.7 The Effect of Pressure Changes on Equilibrium

Question 1

What happens to the equilibrium if you increase pressure?

Answer 1

• equilibrium moves to the side with fewest gas molecules (number of molecules shown by balanced equation)
• to reduce pressure

Question 2

What happens to the equilibrium if you decrease pressure?

Answer 2

• equilibrium moves to the side with most gas molecules (number of molecules shown by balanced equation)
• to increase pressure
