18 LeChatelier’s principle can be used to predict the

(1) reactivity of a metal

(2) volume of a gas at STP

(3) concentration of an aqueous solution

(4) effect of a stress on a system at equilibrium

Solution:

Le Chatelier's principle states that if there is a stress on a system that takes it away from the equibrium position, the system will react in such as way as to reestablish the equilibrium. Choice 4 is the correct answer.
