The vander waal gas constant `'a'` is given by

A

`(1)/(3) V_(C)`

B

`3P_(C) V_(C)^(2)`

C

`(1)/(8) (RT_(C))/(P_(C))`

D

`(27)/(64) (R^(2) T_(C)^(2))/(P_(C))`

Text Solution

Verified by Experts

The correct Answer is:
B, D
`a = (9)/(8) RT_(C) V_(C) = (27 R^(2) T_(C)^(2))/(64P_(C)) = 3P_(C) V_(C)^(2)`
