Le Châtelier’s principle <ul><li>Explain how Le Châtelier’s principle applies to equilibrium systems. </li></ul>When changes are made to a system at equilibrium, the system shifts to a new equilibrium position.
  19. 20. Section 17-2 Le Châtelier’s Principle <ul><li>Le Châtelier’s Principle was proposed in 1888 and states that if stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress. </li></ul><ul><li>Stress is any kind of change in a system that upsets the equilibrium. </li></ul>
  20. 21. Section 17-2 Le Châtelier’s Principle (cont.) <ul><li>Adjusting the concentrations of either the reactants or the products puts stress on a system in equilibrium. </li></ul><ul><li>Adding reactants increases the number of effective collisions between molecules and upsets the equilibrium. </li></ul>
  21. 22. Section 17-2 Le Châtelier’s Principle (cont.) <ul><li>The equilibrium shifts to the right to produce more products. </li></ul><ul><li>Stress is relieved by shifting to the left, converting products to reactants. </li></ul>
  22. 23. Section 17-2 Le Châtelier’s Principle (cont.) <ul><li>Increasing pressure shifts the system to the left, and more products are formed. </li></ul><ul><li>Changing the volume (and pressure) of an equilibrium system shifts the equilibrium only if the number of moles of gaseous reactants is different from the moles of gaseous products. </li></ul><ul><li>If the number of moles is the same on both sides of the balanced equation, changes in pressure and volume have no effect on the equilibrium. </li></ul>
  23. 24. Section 17-2 Le Châtelier’s Principle (cont.) Lowering the piston decreases the volume and increases the pressure. The reaction between CO and H 2 is at equilibrium. As a result, more molecules of the products form. Their formation relieves the stress on the system.
