Solution

The correct option is C When $Z > 1$ , real gases are difficult to compress
When $Z > 1$ , real gases are difficult to compress because the forces of attraction between the molecules are very feeble.

Q. Assertion :Compressibility factor Z according to van der Waal's equation may be written as

Z = \frac{1}{1 - (\frac{n b}{V})} - \frac{a n}{R T V}

. Reason: For real gases

Z >< 1

The gases which strictly follow the general equation

(P V = n R T)

are called ideal or perfect gases. Actually, there is no gas which is perfect or ideal. A real gas is one which actually exists, whether it obeys gas laws strictly or not. Under ordinary conditions, only those gases nearly behave as ideal or perfect which have very low boiling points such as nitrogen, hydrogen, etc. The most easily liquefiable and highly soluble gases such as ammonia, carbon dioxide, sulphur dioxide show large deviations.
A very convenient method of studying deviation of real gases from ideal behaviour is through a compressibility factor

(Z)

Z = \frac{P V}{n R T}

(i)

Z = 1

, for ideal gases.
(ii)

Z \neq 1

, for real gases.
