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.

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