Which one is not correct for gaseous state obeying van der Waals equation?

A

Compressibility factor at critical temperature `=0.375`

B

For a gas if van der Waals' constant `a= 0, T_(c )= 0`

C

Ideal gases do not have critical temperature

D

Gaseous molecules showing H-bonding show minimum deviations from `Z = 0.375`.

Text Solution

Verified by Experts

The correct Answer is:
D
`(P_(C )V_(C ))/(T_C)= (3R)/(8)`, Also molecules showing H-Bonding show maximum deviations in Z due to increase in molecular attractions `(e.g., Z" for "NH_(3), H_(2)O, CH_(3)OH approx 0.22 " to "0.24`).
