							N2+3h2=2nh3
Here N2 is the limiting Reagent.
Therefore, moles of NH3 is=> 1*2 => 2 moles.
Now H2O is added,
Hence the reacn. becomes,
NH3  +   H2O  --------------->        NH4OH
2 mol                                           2 mol.
Hence Total pressure in flask woould be,
P*15 = 2*R*300
P = 600R/15 => 40R atm
      or
 => 40 * 0.0821
 => 3.284 atm.

Here, 2 moles of NH3 is formed and 1 mole of H2 is leftover.
Also, since 5 litre of water is added, Vol=10L.
P= (1*0.0821*300)/10=2.463atm
