Ammonia gas at 76 cm Hg pressure was connected to a manometer. After sparking in the flask, ammonia is partially dissociated as follows : `2NH_(3) (g) hArr N_(2) (g) + 3H_(2) (g)` the level in the mercury column of the manometer was found to show the difference of 18 cm. What is the partial pressure of `H_(2) (g)` at equilibrium ?
