Out of `NH_3` and `N_2`, which one will have greater value of the van dar Waal's constant 'a'

Text Solution

Verified by Experts

As `NH_3` is more easily liquifiable ( due to hydrogen bonding), intermolecular forces of attration are stronger in `NH_3` than `N_2`. Hence `NH_3` will have greater value of .a.. As `NH_3` molecule is larger in size than `N_2`, `NH_3` will have greater value of .b..
