Consider the van der Waals constants, a ...

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

A

Kr

B

Ne

C

Ar

D

Xe

Text Solution

Verified by Experts

The correct Answer is:
A
`T_(c )=(8a)/(27Rb) or prop (a)/(b)`
`"Larger the value of "(a)/(b)," higher is "T_(c )`
`"Ar :"(1.3)/(3.2)=0.406, Ne:(0.2)/(1.7)=0.118`
`"Kr : (5.1)/(1)=5.1, Xe:(4.1)/(5.1)=0.82`
`therefore" Kr will have highest T"_(c )`.
