Chemistry - Real Gas Question with Solution | TestHub

For real gases, the $PV$ versus $P$ diagram at a constant temperature is not linear. Therefore, $\frac{d}{P}$or $\frac{w}{VP}$ will not be independent of $P$. (where $w$ is the mass of gas, $V$ is the volume, and $P$ is the pressure).

Given: Critical volume ($V_c$) $=0.675d{m}^{3}mo{l}^{-1}$, molar mass of gas $=90gmo{l}^{-1}$, $R=\frac{1}{12}Latmmo{l}^{-1}{K}^{-1}$.

At high $P$, a $\frac{d}{P}$ versus $P$ graph is plotted at $540K$. (Assume $\frac{Pb}{RT}\ll 1$).

The magnitude of the slope of the graph is _______.
