Three cylinders connected with valves are shown in the diagram. All the cylinders are at the same temperature. Which of the following statements are true once the valves are opened and the system is allowed to reach equilibrium, given that the volume of connecting tubes may be neglected

A

Total pressure of the system will be 1.75 atm

B

The partial pressure of Ne in cylinder 1 will be higher than that in cylinder 2 and 3

C

The correct order of partial pressures will be $$p(\text{Ne}) > p(\text{Xe}) > p(\text{Ar})$$

D

Number of moles of gas in cylinder 2 will be lower than its initial value.
