Vedclass · Answer

(D) Real gases deviate from ideal behavior because of intermolecular forces and the finite volume of gas molecules.This deviation is most significant under conditions of low temperature and high pressure.Comparing the given options,the condition with the lowest temperature $(-13\,^{\circ}C)$ and the highest pressure $(2\, atm)$ will show the maximum deviation from ideal behavior.Therefore,the correct option is $D$.

Gas	$a / (kPa \cdot dm^6 \cdot mol^{-2})$	$b / (dm^3 \cdot mol^{-1})$
$A$	$642.32$	$0.05196$
$B$	$155.21$	$0.04136$
$C$	$431.91$	$0.05196$
$D$	$155.21$	$0.4382$
