How does a decrease in the volume of a container affect the equilibrium of a reaction involving gases?

A. Shifts the equilibrium to the side with fewer gas molecules
B. Shifts the equilibrium to the side with more gas molecules
C. Has no effect
D. Stops the reaction

Answer: Shifts the equilibrium to the side with fewer gas molecules


Additional Information: Decreasing the volume increases pressure, favoring the side with fewer gas molecules.
