In Vander Waal's equation of state for a non-ideal gas, the term that accounts for intermolecular forces is [CBSE PMT 1990; IIT 1988]

In the equation  \(           \left[ p+\frac{an^2}{v^2} \right]  \left[    V-nb    \right]  =nRT    \)  ''b'' represents MDCAT2017

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]

In which molecule the vander Waal’s force is likely to be the most important in determining the m.pt. and b.pt. [DPMT 2000]

In van der Waal’s equation of state of the gas law, the constant ‘ b ’ is a measure of [AIEEE 2004]
