At a given temperature T, gases Ne, Ar, Xe and Kr are found to deviate from ideal gas behavior. Their equation of state is given
as 
at T.
Here, 
is the van der Waals constant. Which gas will exhibit steepest increase in the plot of Z (compression factor) vs P ?
Text Solution
Verified by ExpertsThe correct answer is:
A
JEE Main 2019
[Where Z (compressibility factor) 
]
Slope of Z vs P curve (straight line) 
Higher the value of b, more steep will be the curve.
Constant ‘b’ value depends on size of atom or molecule.
