• Concentration
• Pressure
• Temperature
• States of matter

2SO₂(g)+O₂(g)⇌2SO₃(g)

Removing O₂(g) will

• shift equilibrium right

• shift equilibrium left

• increase pressure

• have no change

2SO₂(g)+O₂(g)⇌2SO₃(g)
Increasing volume of container will

• shift equilibrium right
• shift equilibrium left
• slow rate of reaction
• have no change

2SO₂(g)+O₂(g)⇌2SO₃(g)
Decreasing volume of container will

• shift equilibrium right
• shift equilibrium left
• change K
• have no change

For N₂ + 3H₂ →2NH₃ . When pressure is increased the equilibrium shift to right. Why?

• To increase the amount of products

• To reduce the pressure, as right has less number of moles

• K_c will increase when it is shifted to the right

• So it will increase the rate of reaction

Le Chatelier'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
