Vedclass · Answer

(A) In the ideal gas equation,we neglect the intermolecular attractions and the volume occupied by molecules. However,the real gas equation accounts for both of these. The parameter $a$ is a measure of intermolecular attraction,and the parameter $b$ is a measure of the volume occupied by the molecules. In particular,if the volume of a single gas molecule is $v$,then $b = 4vN_A$. Hence,$b$ is four times the molar volume of the gas molecules.

In van der Waals equation of state,the constant $b$ is a measure of
