Lab 8 - equilibrium and le châtelier's principle associated with the equilibrium induces a stress on the system if a stress is applied, the system will shift to. When some stress is applied to a system originally in equilibrium, the system (reaction) automatically will shift in such a direction as to relieve the stress (in this example a change in concentrations) and restore the original conditions as much as possible.
