Consider the van der Waals' constants, a and b, for the following gases:
`{:(gas, Ar, Ne, Kr, Xe),(a//(atm " dm"^6 mol^(-2)),1.3,0.2,5.1,4.1),(b//(10^(-2)dm^3 mol^(-1)),3.2,1.7,1.0,5.0):}`
Which gas is expected to have the highest critical temperature?

A

Ar

B

Ne

C

Kr

D

Xe

Text Solution

Verified by Experts

The correct Answer is:
C
`T_(C) = (8a)/(27Rb)`, For Kr the value of `((a)/(b))` is highest , Thus `T_(C)` is also highest
