Vedclass · Answer

(B) The compressibility factor $z$ is defined as $z = \frac{PV}{nRT}$.For real gases, the deviation from ideal behavior depends on the magnitude of intermolecular attractive forces.$CO_2$ is a gas with relatively strong intermolecular forces compared to $H_2, He,$ and $N_2$, leading to a more significant negative deviation $(z Among the given curves, the curve that shows the deepest dip below the ideal line $(z = 1)$ corresponds to the gas with the strongest attractive forces.Therefore, curve $A$ represents $SO_2$, curve $B$ represents $CO_2$, curve $C$ represents $N_2$, and curve $D$ represents $H_2$ (which shows $z > 1$ due to dominant repulsive forces).Thus, the plot for $CO_2$ gas is $B$.

$A$ plot of the compressibility factor $(z)$ vs $P$ is shown below for $H_2, He, N_2, CO_2$ and $SO_2$. Identify the plot for $CO_2$ gas.
