For a gas,the deviation from ideal behavior is maximum at:

According to the $van \ der \ Waals$ equation of state,the pressure exerted by gas molecules on the walls of a container depends on which of the following factors?

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 values of the van der Waals constant $a$ for gases $O_2, N_2, NH_3$,and $CH_4$ are $1.360, 1.390, 4.170$,and $2.253 \ L^2 \ atm \ mol^{-2}$ respectively. Which gas can be liquefied most easily?

Define the compressibility factor $(Z)$ in terms of the molar volume of a gas.

The pressure exerted by $5 \ mol$ of a real gas in a $1 \ L$ container at $47 \ ^oC$ is ......... $atm$. (Given: $a = 3.592 \ atm \ L^2 \ mol^{-2}$,$b = 0.0427 \ L \ mol^{-1}$)
