At a given temperature T, gases Ne, Ar, Xe and Kr are found to deviate from ideal gas behaviour. Their equation of state is given as \[p=\frac{RT}{V-b}\]at T. Here, b is the van der Waals constant. Which gas will exhibit steepest increase in the plot of Z (compression factor) vs p? [JEE Main 9-4-2019 Afternoon]

A) Ne                               

B) Ar

C) Xe

D) Kr

Correct Answer: C

Solution :

            \[As\,b\uparrow \Rightarrow slope\,\uparrow \]  Hence, Xe, will have highest slope
