Equilibrium and Le Chatelier

2SO_2(g)+O_2(g) ⇌ 2SO_3(g) + Heat

Adding SO_2(g) will

• shift equilibrium right

• shift equilibrium left

• increase rate of reaction

• have no change

• 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

What happens to the equilibrium if we add methane (CH₄)?

What does Le Chatelier's Principle state about a system at equilibrium when it is subjected to a change in concentration, temperature, or pressure?

• The system will shift in the direction that increases the change.

• The system will remain unchanged.

• The system will shift in the direction that opposes the change.

• The system will shift in random directions until a new equilibrium is established.

What is the effect of adding more reactant to a system at equilibrium?

• It will shift the equilibrium towards the products.

• It will shift the equilibrium towards the reactants.

• It will not affect the equilibrium position.

According to Le Chatelier's Principle, if the concentration of a reactant is increased, the equilibrium of the reaction will:

• Shift to the left, favoring the formation of reactants

• Shift to the right, favoring the formation of products

• Remain unchanged

• Increase the overall reaction rate without shifting the equilibrium

Le Chaltelier's Principle states that if a chemical system at equilibrium is stressed,

• the system will adjust to increase the stress

• the system will adjust to reduce the stress

• the system will not adjust
