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 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 ?
Xe
Kr
Ne
Ar
Compressibility Factor -
used to find deviation of a gas from ideal behaviour
-
Compressibility Factor -
-
Compressibility Factor -
For ideal gas Z=1
-
Compressibility Factor -
at low pressures, all gases have Z less than 1.
-
Compressibility Factor -
at very high pressure, all gases have Z greater than 1.
-
Compressibility Factor -
for hydrogen and helium, Z is greater than 1 even at low pressures.
-
we know , at T=Constant
( volume of molecules )
order of radii of element
b value of Xe will be higher so , the graph will be steepest .
Xe
Option 2)Kr
Option 3)Ne
Option 4)Ar
