A very convenient method of study in PV deviation of real gases from ideal behaviour is through a compressibility factor (Z), Z= `(PV)/(nRT)`
i) Z=1, for ideal gases , ii) Z+1, for real gases
The behaviour of a real gas is usually depicted by plotting compressibility factor Z versus pressure P at a constant temperature. At high temperature and pressure, Z is usually more than one. This fact can be explained by van der Waal's equation when: the constant`a` is negligible but not`b`, the constant `b` is negligible but not `a`, both the constants `a` and `b` are negligible, both the constants `a` and `b` are not negligible

A

the constant'a' is negligible but not'b'

B

the constant 'b' is negligible but not 'a'

C

both the constants 'a' and 'b' are negligible

D

both the constants 'a' and 'b' are not negligible
