Question

A manometer attached to a flask contains with ammonia gas have no difference in mercury level initially as shown in diagram. After sparking into the flask, ammonia is partially dissociated as $2 N H_{3} (g) \to N_{2} (g) + 3 H_{2} (g)$ now it have difference of 6 cm in mercury level in two columns, what is partial pressure of $H_{2} (g)$ at equilibrium?

Answer: aSolution: (a)

(a) Before sparking After sparking at eqm 2 N H_{3} (g) 76 76 - 2 x \to N_{2} (g) 0 x + 3 H_{2} (g) 0 3 x

Increase in pressure

2 x = 6, x = 3 c m H g

Partial pressure of

H_{2} = 3 \times 3 = 9 c m H g
