Dalton's law of partial pressures is not applicable to

Two closed vessel A and B of equal volume of 8.21 L are connected by a narrow tube of negligible volume with open valve. The left hand side container is found to contain 3 mole $CO_{2}$ and 2 mole of He at 400 K. What is the partial pressure of He in vessel B at 400 K?

For a gas obeying the van der Waals' equation, at the critical point

A capillary tube of radius $0.4mm$ is dipped vertically in water. Find up to what height the water will rise in capillary. If the capillary is inclined at an angle of of $60$ degree with the vertical, how much length of the capillary is occupied by water? Surface tension of water is $7.0×10$ to the power $−2N$ per meter.

If a gas espands at a constant pressure by providing heat :

A compressed cylinder of gas contains $1.50×10_{3}$ g of $N_{2}$ gas at a pressure of $2.0×10_{7}$ Pa and a temperature of $17.1_{∘}C$. What volume of gas has been released into the atmosphere if the final pressure in the cylinder is $1.80×10_{5}$ Pa ? Assume ideal behaviour and that the gas temperature is unchanged.

which in not correct curve for Gay-luacc's law ?

A rigid vessel of volume $0.50m_{3}$ containing $H_{2}$ at $20.5_{∘}C$ and a pressure of $611×10_{3}$ Pa is connected to a second rigid vessel of volume 0.75$m_{3}$ containing Ar at $31.2_{∘}C$ at a pressure of $433×10_{3}$ Pa. A value separating the two vessels is opened and both are cooled to a temperature of $14.5_{∘}C$. What is the final pressure in the vessels?
