Compressibility factor, Z, of a gas is given as Z = (pV/nRT)
(i) What is the value of Z for an ideal gas?
(ii) For real gas what will be the effect on value of Z above Boyle’s temperature?
(i) Z is a compressibility factor. Its value for an ideal gas is Z = 1.
(ii) Real gases show positive deviation above Boyle's temperature, i.e., Z>1.
