Le Chatelier's Principle and Equilibrium Shifts 1. If the reaction below is initially at equilibrium, and then each of the following changes are made, predict which direction the reaction rate will be fastest until equilibrium is once again established: forward, reverse, or no change. Reactant 2COg+O2g) # 2 CO2(g) a. The concentration of O₂ is increased. -forward, reactant b. The concentration of CO₂ is decreased? forwardl, eactant c. The concentration of oxygen gas is decreased. reverse, product Product 2. If the reaction below is initially at equilibrium, and then each of the following changes are made, predict which direction the reaction rate will be fastest until equilibrium is once again established: forward, reverse, or no change. Reactant C(s) + H₂O(g) a. adding H₂0) forward. b. removing H₂ forward decrea. adding PC13 reverse increasc b. removing Ch₂ forward increast c. removing PC13 forward decreased. adding Cl₂ reverse Product CO(g) + H2(g) 3.

Change Made to a Reaction that was at Equilibrium: Increase the concentration of a reactant. Increase the concentration of a product. Decrease the concentration of a reactant. Decrease the concentration of a product. Response: Rate of the forward reaction becomes greater than the rate of the reverse reaction until equilibrium is reestablished. Rate of the reverse reaction becomes greater than the rate of the forward reaction until equilibrium is reestablished. Rate of the forward reaction becomes less than the rate of the reverse reaction until equilibrium is reestablished. Rate of the reverse reaction becomes less than the rate of the forward reaction until equilibrium is reestablished.
