A gas described by van der Waals equation :

A

behaves similar to an ideal gas in the limit of larger molar volumes

B

behaves similar to an ideal gas is in limit of larger pressure

C

is characterised by van der Waals coefficients that are dependent on the identify of the gas but an independent of the temperature.

D

has the pressure that is lower than the pressure exerted by same gas behaving ideally

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
(A) At very large molar volume `P +(a)/(V_(m)^(2)) ~~ P` and `V_(m) -b = V_(m)`.
(C ) According to van der Waals equation 'a' and 'b' are independent of tempt.
