Le Chatelier's Principle
Apply Le Chatelier's Principle to predict how chemical equilibria shift in response to stress. Visualize how changes in concentration, pressure, volume, or temperature cause the system to counteract the disturbance and establish a new equilibrium. Explore the Haber Process for ammonia synthesis, understand why increasing pressure favors fewer moles of gas, and learn how catalysts speed up equilibrium attainment without shifting position.
