Question#2
In the equation \( \left[ p+\frac{an^2}{v^2} \right] \left[ V-nb \right] =nRT \) ''b'' represents MDCAT2017
Question#3
The Vander Waal's constant 'a' for the gases O2 , N2 , NH3 and
CH4
are \( 1.3, 1.390, 4.170 \)and \(2.253 L^2 atm mol^{-2}\) respectively.
The gas which can be most easily liquefied is
[IIT 1989]
Non-ideal behavior of gases \(\propto\) a
Non ideal behavior of gases \(\propto\) liquefaction of gases

at [Kerala MEE 2001; CBSE PMT 2002]
Question#7
Vander Waal's constants \('a'\) and \( 'b'\) are related with..... respectively[RPMT 1994]
?For an ideal gas
- There are no forces of attraction between gas molecules i.e \(a\)=0
- Volume of molecules 4Vm= b is negligible as compare to whole volume i.e \(b=O\)
