Question

(B) The deviation from ideal behavior occurs because the assumptions of the Kinetic Molecular Theory of gases are not perfectly valid for real gases.$

Vedclass · Accepted Answer

Due to the finite size of gas molecules and intermolecular interactions.

Vedclass · Answer

(B) The deviation from ideal behavior occurs because the assumptions of the Kinetic Molecular Theory of gases are not perfectly valid for real gases.$1$. The assumption that there are no intermolecular forces of attraction is incorrect; in reality,gas molecules experience intermolecular forces (attraction and repulsion).$2$. The assumption that the volume occupied by gas molecules is negligible compared to the total volume of the gas is incorrect; at high pressure and low temperature,the molecular volume becomes significant,leading to deviations.

Gas	$Ar$	$Ne$	$Kr$	$Xe$
$a \ (atm \ dm^6 \ mol^{-2})$	$1.3$	$0.2$	$5.1$	$4.1$
$b \ (10^{-2} \ dm^3 \ mol^{-1})$	$3.2$	$1.7$	$1.0$	$5.0$

Why do real gases deviate from ideal behavior in the $pV$ vs $p$ and $p$ vs $V$ graphs at specific temperatures?
