Why does the equilibrium of a system shift when the pressure is decreased? To maximize the stress on the system. To stop restoring equilibrium to the system. To increase the total moles of gas in the system. To decrease the total moles of gas in the system.

To increase the total moles of gas in the system.

Explanation:

Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.

This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.

If the pressure is reduced, the volume will increase according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where increase in pressure is taking place. So, the equilibrium will shift in the direction where the number of moles of gas molecules is greater.
