Why is the intermolecular attraction ball predominant if the contraction coefficient is Z <1 ?

Description : Why is the intermolecular attraction ball predominant if the contraction coefficient is Z

Last Answer : Z < 1 means that real gas is more compressible than standard gas. If a gas is more compressible , the intermolecular attraction between the gas particles must be greater. This is why if z < 1, the intermolecular force of attraction is greater , so that the gas becomes more compressible.
