August 2018 NY Regents Chemistry Exam
24 For a reaction system at equilibrium, LeChatelier’s principle can be used to predict the (1) activation energy for the system
(2) type of bonds in the reactants (3) effect of a stress on the system
(4) polarity of the product molecules
Solution: Le Chatelier's principle states that when there is a stress on the system that takes it away from the equilibrium, the system will react in such a way to reestablish the equilibrium.
