Chemistry Question on States of matter

The temperature ar which a real gas obeys the ideal gas laws over a wide range of pressure is

A

critical temperature

B

Boyle temperature

C

inversion temperature

D

reduced temperature

Answer

Boyle temperature

Explanation

Solution

It is the Boyle temperature TB.T_B. At Boyle temperature, the first virial coefficient (B) vanishes and real gas approaches ideal behaviour.
TB=aRb\, \, \, \, \, \, \, \, \, \, \, \, \, \, \, T_B=\frac{a}{Rb}
Here, a and bare van der Waals' constants.
