An open manometer attached to a Flash Contrining Ammonia gas have No difference in mercury level initally as stowns in diagram. Aftor sparting into the flash, Ammonio is Partially desiociated as -

\mathrm{2NH}_{3}(g) \longrightarrow \mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(g)
Now it have difference of \mathrm{16 \mathrm{~cm}} in mercury level in two columns. what is the Partial pressure of \mathrm{H_{2} (g)} at equilibrium?

Option: 1

24 \mathrm{~cm}$ at $\mathrm{Hg}


Option: 2

27 \mathrm{~cm}$ at $\mathrm{Hg}


Option: 3

9 \mathrm{~cm}$ at $\mathrm{Hg}


Option: 4

2 \mathrm{NH}_{3}(\mathrm{~g}) \longrightarrow \mathrm{N}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{~g})
76-2x                         x                3x

76+2 = 76+16
2 x =16
x =8

\mathrm{P_{H_{2}} =3 x=3 \times 8=24 \mathrm{~cm} \text { at } \mathrm{Hg}}
