Compressibility factor (Z): Real gases deviate from ideal behavior due to the following two faulty assumptions of kinetic theory of gases.
i)Actual volume occupied by the gas molecule is negligible as compared to the total volume of the gases.
ii)Forces of attraction and repulsion among the gas molecules are negligible.
the, extent of deviation of the real gas from ideal behaviour, is explained in terms of compressibility factor (Z), which is function of pressure and temperature for real gas.
For ideal gas, Z = 1
For real gases, Z > 1 or Z < 1
When Z > 1, then it is less compressible because force of repulsion dominates over force of attraction when Z < 1, force of attraction dominates over the force repulsion.
Graph in between Z & P is shown as under
On increasing temperature, Z increases and approaches to unity. Graph between
Z and P at different temperature for the same gas is shown as under:
