O none of these O The amount of SO3(g) decreases and the value for K stays the same. O The amount of SO3(g) increases and the value for K stays the same. Which statement best represents LeChatelier's Principle? O none of these O A system in equilibrium will respond to a change by moving in the direction that reduces the change as it returns to equilibrium. O A system in equilibrium will always remain in equilibrium. O 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. Of the following questions, which ones are thermodynamic rather than kinetic concepts? I.
