Question 33 1 pts Which statement best represents LeChatelier's Principle? none of these A system in equilibrium will respond to a change by moving in the direction that reduces the change as it returns to equilibrium. A system in equilibrium will always remain in equilibrium. A system in equilibrium will not be affected by a change in concentration. O When a change is made to a system in equilibrium, equilibrium can never be restored.
