Le Chatelier's principle states that when a system at equilibrium is disturbed, the system will shift in the direction that will reduce the stress. Use the reaction above, and decide how the system will shift to oppose the stresses below. Column A 1. More PCl3 (phosphorus trichloride) is added to the system. : More PCl3 (phosphorus trichloride) is added to the system. 2. The temperature of the system is decreased when heat is removed from the system.: The temperature of the system is decreased when heat is removed from the system. 3. More PCl5 (phosphorous pentachloride) is added to the system. : More PCl5 (phosphorous pentachloride) is added to the system. 4. The temperature of the system is increased when more heat is added.: The temperature of the system is increased when more heat is added. 5. PCl5 (phosphorous pentachloride) is removed from the system. : PCl5 (phosphorous pentachloride) is removed from the system. 6. Chlorine (Cl2) is removed from the system. : Chlorine (Cl2) is removed from the system. Column B a.The system will shift right, towards the products. b.The system will shift left, towards the reactants.
