Calculate the compressibility factor for $SO_2$,if $1 \ mol$ of it occupies $0.35 \ L$ at $300 \ K$ and $50 \ atm$ pressure.

Among the following,the maximum deviation from ideal gas behavior is expected from

At very high pressures,the compressibility factor of one mole of a gas is given by

The Van der Waals constant '$a$' for the gases $O_2$,$N_2$,$NH_3$ and $CH_4$ are $1.3$,$1.390$,$4.170$ and $2.253 \ L^2 \ atm \ mol^{-2}$ respectively. The gas which can be most easily liquefied is

The deviation will be maximum in the behaviour of a gas from the ideal gas equation $PV = nRT$?

The compressibility factor for a real gas at high pressure is :-
