Tc= Temperature at and above which the vapour state can not be further liquified.
Pc= Pressure of gas in its critical state
Vc= Volume of gas in its critical state.
relation with the van der waals constants -
Tc=8a/27Rb So a=27TcRb/8
Vc=3b So b=Vc/3
put the value of a and b in equation (1)

A sample of ideal gas of some mass is taken through the cyclic process shown in the figure. The temperature of the gas at state A is TA = 200K, and at state C is TC = 1800K. Choose the correct option(s).
The volume occupied by 2 mol of N2 at 200 K and 10.1325 MPa pressure is
(Given that PcVCRTC=38 and PrVrTr=2.21 ), where Pr,Vr and Tr are reduced pressure, reduced volume and reduced temperature.
The vander waal's equation of corresponding states for 1 mole of gas is [where Pc= critical pressure, Tc= critical temperature, Vc= critical volume] [π=PPc,ϕ=VVcandθ=TTc]
If PPc=x (reduced pressure), VVc=y (reduced volume) and TTc=z (reduced temperature), then,
Tc and Pc of a gas are 400K and 41 atm respectively, Vc is:
