Question

A definite amount of solid NH 4 ​ HS is placed in a flask already containing ammonia gas at a certain temperature and 0.50 atm pressure. NH 4 ​ HS decomposes to give NH 3 ​ and H 2 ​ S and at equilibrium total pressure in flask is 0.84 atm . The equilibrium constant in atm 2 for the reaction is

TestHub · Accepted Answer

NH₄HS(s) ⇌ NH₃(g) + H₂S(g) Initially: 0.5 0 At equilibrium: 0.5 + p , p ( 0.5 + p ) + p + = 0.84 p = 0.17 a t m K p ​ = 0.67 × 0.17 K p ​ = 0.114 a t m 2
