Compressibility Factor

Determine which of the following statements are true at very high pressure for a real gas: (a) Compressibility factor is greater than 1. (b) Compressibility factor varies linearly with pressure. (c) Molar volume occupied by gas is more as compared to ideal gas at similar pressure and temperature. (d) Gas is less compressible as compare to ideal gas. (e) Compressibility factor is given by Z=1+(Pb)/(RT) .

For critical constant factor, compression factor Z is
