${N_{2(g)}} + 3{H_{2(g)}} \rightleftharpoons \,2N{H_{3(g)}}$ at equilibrium at constant volume will lead to
(Given : $h =6.63 \times 10^{-34} \,Js , N _{ A }=6.02 \times 10^{23} \,mol ^{-1}$, $c =3 \times 10^{8}\, ms ^{-1}$ )

(Use molar mass of aluminium as $27.0 g mol ^{-1}, R =0.082 atm L mol { }^{-1} K ^{-1}$ )
