How is compressibility factor Z related to the real and ideal volume of the gas?
Z = P Vreal nRT …(1) If the gas shows ideal behaviour, then Videal = nRTP ….(2) On putting the titis value of nRT in equation (1), we get Z = Vreal Videal Thus the compressibility factor Z is the ratio of the actual molar volume of a gas to the molar volume of it. if it were an ideal gas at that temperature and pressure.
