Le Châtelier's Principle “If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or total pressure, then the equilibrium shifts to partially counteract the imposed changethe equilibrium shifts to partially counteract the imposed change ”
Le Châtelier's Principle: Changing Concentration Add more N02 N204(g) 2 N02(g) Add N02 2 N02(g) More Equilibrium forms is disturbed 2 N02(g) N204(g) System shifts left A FIGURE 14 9 Le Châtelier's Principle: The Effect of a Concentration Change Adding N02 the reaction to shift left, consummg some of the added N02 and forming more N204
Le Châtelier’s Principle Page 2 of 15 For chemical reactions at equilibrium in aqueous solution, the most common types of perturbations include changing the concentration of one of the aqueous solutes, changing the concentrations of all aqueous solutes by changing the total solution volume, or changing the temperature
Le Chatelier’s Principle is lowered by increasing the volume of the reaction container a Equilibrium will produce more N 2O 4 (g) to offset the pressure

Le Chatelier’s Principle The Effect of Temperature on Equilibrium Le Chatelier’s Principle states that if a system at equilibrium is subjected to a change of conditions, reactions occur in the system that tend to counteract the imposed change In other words, the system tends to react in a way that restores the equilibrium When the imposed stress

e) Adding helium at constant volume: Since the volume of the container remains constant, the concentration of the gases also remains constant Therefore no stress has been applied and the equilibrium is unaffected f) Adding helium at constant pressure: In order for pressure to remain constant, the volume of the container must increase The equilibrium will shift left to produce more gas molecules
