Directions For Questions

The extent of deviation of real gases from ideal behaviour, can be expressed in terms of compressibility factor (Z). Corrected ideal gas equation for real gases can be written as:

PV = nZRT

Where symbols have their usual meaning.

The reasons of deviation of real gases from ideal behaviour can be explained by kinetic theory of gases. For a real gas, compressibility factor (Z) have different values in different pressure zones, but its value is fixed at critical state.
