Vedclass · Answer

(C) The compressibility factor $(Z)$ is defined as $Z = \frac{PV}{nRT}$. For non-ideal gases,$Z$ can be greater than $1$ (when repulsive forces dominate) or less than $1$ (when attractive forces dominate). Therefore,the Assertion is correct.Non-ideal gases do not always exert higher pressure than expected. Due to intermolecular attractive forces,the pressure exerted by a real gas is generally lower than the pressure predicted by the ideal gas law $(P_{real} < P_{ideal})$. Thus,the Reason is incorrect.

Assertion : Compressibility factor $(Z)$ for non-ideal gases can be greater than $1$.
Reason : Non-ideal gases always exert higher pressure than expected.
