\[N{{H}_{3}}\]gas is liquefied more easily than \[{{N}_{2}}\]. Hence

A)  van der Waals' constants a and b of \[N{{H}_{3}}\] \[>\] that of \[{{N}_{2}}\]

B)  van der Waals' constants a and b of \[N{{H}_{3}}\] \[<\] that of \[{{N}_{2}}\]

C)  a(\[N{{H}_{3}}\]) \[>\] a(\[{{N}_{2}}\]) but b(\[N{{H}_{3}}\]) \[<\] b(\[{{N}_{2}}\])

D)  a(\[N{{H}_{3}}\])\[<\] a(\[{{N}_{2}}\]) but b (\[N{{H}_{3}}\]) \[>\] b(\[{{N}_{2}}\])
