What does Le Chartelier's principle tell us?

• The equilibrium shifts in the same direction to enhance the change and reestablish a new equilibrium.

• The equilibrium shifts in the opposite direction to offset the change and reestablish a new equilibrium.

• None of the above

Le Chartelier's principle applies on both forward and reversible reactions
