Dear Shivani
 
The reaction is
                                             N2  +  3H2  ⇌  2NH3
Initial moles                         1          3            0
Nos of moles at eqm       1-y      1-3y         2y
​
Kc = 4/27
4/27 = (2y)²/ (1-y)(1-3y)³
 
Now solve this
 
You can simply calculate y and then concentration of NH3.
