A mixture of three gases P (density 0.90), Q (density 0.178) and R (density 0.42) is enclosed in a vessel at the constant temperature. When the equilibrium is established:
the gas P will be at the top of the vessel
the gas Q will be at the top of the vessel
the gas R will be at the top of the vessel
the gases will mix homogeneously throughout the vessel.
A
the gas R will be at the top of the vessel
B
the gas P will be at the top of the vessel
C
the gas Q will be at the top of the vessel
D
the gases will mix homogeneously throughout the vessel.

Independent of density of gases, in equilibrium gases will mix homogenously, this comes from the fact that gases occupies entire volume of container. This also can be thought as gases tries to reduce energy. Hence they separate as far as possible.
