Consider the following statements If th van der Waals' parameters of two gases are given as
`{:(,a//dm^(6)"bar"mol^(-2),b//dm^(3)mol^(-1),,),(GasA,6.5,0.056,,),(GasB,18.0,0.011,,):}`
then which of the following statements is//are correct ? .

Options

A. Critical volume of `A lt` Critical volume of `B`
B. Critical Pressure of `A lt` Critical volume of `B`
C. Critical temperature `A lt` Critical temperature of `B`
D. All of these

Explanation

`T_(c)` for gas having low a will be less. Also
`P_(c) =(a)/(27b^(2')) T_(c) (8a)/(27Rb)` and `V_(c) =3b` .
