The compressibility factor (Z) is defined as (a) real ideal V V (b) P Z nRT (c) ideal real V V (d) nRT Z PV

Compressibility factor real PV Z nRT If the gas shows ideal gas behavior then, ideal nRT V P On putting this value of nRT P in above equation. We have real ideal V z V i.e., compressibility factor is also defined as the ratio of actual molar volume of a gas to the molar volume of ideal gas at that temperature and pressure.
