Adding an inert gas like helium at constant volume has what effect on an equilibrium?
A.No effect
B.Shifts toward fewer gas moles
C.Shifts toward more gas moles
D.Doubles K
Explanation
Core Concept
At constant volume, adding inert gas raises total pressure but changes no reactant/product partial pressures, so Q stays equal to K and nothing shifts.
Correct Answer
ANo effect
