Which of the following does not affect the position of equilibrium?

• Temperature

• Pressure

• Particle Size

• Concentration

How does a catalyst affect the position of the equilibrium?

• It does not. It only increases the rate of reaction.

• Position of equilibrium will shift to the right.

• Position of equilibrium will shift to the left.

• The reaction would be slower.

What would be the effect of increasing the temperature to the equilibrium of an exothermic reaction?

• equilibrium shifts to the left

• equilibrium shifts to the right

• no change in position of equilibrium
