The Chemistry Book

Le Chatelier's Principle is used to predict the effect of a change in conditions on a chemical equilibrium. Henri Le Chatelier suggested that when a system at equilibrium is disturbed, the equilibrium position will shift in the direction which tends to minimize, or counteract, the effect of the disturbance. ^[1]

Analogy: Students find it helpful to think about a teeter totter while working these problems.
