Question

Consider the reaction 2H 2 (g) + O 2 (g)  2H 2 O(g) at some equilibrium position. Using the following choices, indicate what will happen if the changes below are made.

-The size of the reaction vessel is decreased.

Quizplus · Accepted Answer

According to Le Chatelier's principle, if the size of the reaction vessel is decreased, the equilibrium will shift in the direction that produces fewer moles of gas in order to compensate for the decreased volume. In this reaction, the formation of the product 2H₂O(g) produces fewer moles of gas than the reactants, so the equilibrium will shift towards the right to produce more of the product and less of the reactants. Therefore, the equilibrium will shift to the right (choice B).
