A reaction mixture at equilibrium is contained in a cylinder fitted with a movable piston at a constant temperature according to the following equation:

\[ \text{N}_2\text{O}_4(g) \rightleftharpoons 2\,\text{NO}_2(g) \]

The volume of the container is suddenly doubled at constant temperature. Which of the following statements best predicts and justifies the response of the system as it approaches a new equilibrium?
