Le Chatelier's Principle

What will happen when the temperature is increased?

• Position of equilibrium will shift to left and become more blue

• Position of equilibrium will shift to right and become more pink

• No change in position of equilibrium

• Position of equilibrium will shift to left and become more pink

What will happen when OH^- ions are added to the system? HINT: They remove the H+ ions.

• Position of equilibrium will shift to right and become more orange

• Position of equilibrium will shift to left and become more yellow

• Position of equilibrium will shift to right and become more yellow

• OH^- ions will not react, and thus no change is seen.

Increasing the temperature will...

• shift equilibrium right

• shift equilibrium left

• increase pressure

• have no change

2SO_2(g) + O_2(g) ⇌ 2SO_3(g) + Heat

Removing O_2(g) will

• shift equilibrium right

• shift equilibrium left

• increase pressure

• have no change

2SO₂(g)+O₂(g) ⇌ 2SO₃(g) + Heat

Adding SO₃(g) will

• shift equilibrium right

• shift equilibrium left

• increase K

• have no change

Increasing the volume of the container will...

• shift equilibrium right

• shift equilibrium left

• slow rate of reaction

• have no change

2SO₂(g) + O₂(g) ⇌ 2SO₃(g) + Heat

Using a catalyst

• shift equilibrium right

• shift equilibrium left

• increase the rate of reaction

• have no change
