Compare the values of van der waals constants for NH₃ and N₂.Explain why value a is larger for NH₃ but that of b is larger for N₂.

a is larger for NH3 since the the nuclear charge is more and therefore has more attraction than N₂

the constant a is related to intermolecular force it is greater in NH₃ due to H-bonding.

b is related to molecular volume...N₂ takes greater volume
