Le Chateleir

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

At what time (in seconds) is equilibrium established?

• 0 seconds

• 1 second

• 5 seconds

• 2 seconds

What happens to the equilibrium if we remove water (H₂O)?

• It shifts left, towards the reactants

• It shifts right, towards the products

• It does not shift
