Q30 / 90 · JEE Main 2017 (08 Apr Online) · Chemistry

Among the following, the incorrect statement is:

A
at low pressure, real gases show ideal behaviour.
Correct answer
B
at very low temperature, real gases show ideal behaviour.
C
at Boyle's temperature, real gases show ideal behaviour.
D
at very large volume, real gases show ideal behaviour.

Solution

A real gas behaves like ideal gas at high temperature and low pressure. At very low temperature intermolecular forces of attraction will be quite significant as molecular randomness is very low due to which at very low temperature real gases can't show ideal behaviour.

Hence, the correct answer is option: 'B'.
