**Question:**Why does the equilibrium of a system shift when the pressure is decreased?**Options:**- 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**Selected Option:**- To decrease the total moles of gas in the system (Correct answer is highlighted).

According to the Le chatelier's principal, " when a system is already in equilibrium and allowed to perform any stress then the equilibrium shift either of the side to minimize the stress and new equilibrium is established". We know that Pressure is directly proportional to the number of molecules. Therefore when pressure is decreased, the system will try to minimize the strees by increasing pressure i.e. by increasing number of moles. Hence , the equilibrium will shift to increases the total moles of gas in the system. Hence, Answer :- option-(C)
