Select 3 correct answer(s) | Increase the amount of product | Increase the amount of reactant Add a catalyst Decrease the temperature Increase the temperature
MULTIPLE CHOICE Question 11 What does Le Châtelier's principle state? A Equilibrium cannot be re-established once it is disturbed. B A system at equilibrium will remain at equilibrium forever. A system will react to re-establish equilibrium if it is disturbed. A reaction will proceed to completion if equilibrium is disturbed.
Question 20 Which statement best describes general equilibrium? Equilibrium is reached when the reaction stops. There is only one set of equilibrium concentrations that equals the Kc value. At equilibrium, the rate of the forward reaction is the same as the rate of the reverse reaction. At equilibrium, the total concentration of products equals the total concentration of reactants.
