Solution

The correct option is B Vb
In the ideal equation, PiVi=nRT,Vi represents the ideal volume where the molecules can move freely.
In real gases, a part of the total volume is occupied by the gas molecules. Hence the free volume Vi is the total volume V minus the volume occupied by the gas molecules.

i.e. the real volume of gas= Actual volume of the container- volume occupied by N molecules in motion.

Vi=Vb for one mole of gas
Vi=Vnb for n mole of gas

Where b is termed the 'excluded volume' or 'co-volume'.

It is constant and characteristic for each gas.

Hence, option B is correct.
