Question

An amount of solid NH4HS is placed in a closed flask already containing NH3(g) at certain temperature and 0.4 atm pressure. NH4HS decomposes to yield NH3(g) and H2S(g) in the flask. At equilibrium, the total pressure in the flask was found to be 0.64 atm. The equilibrium constant (Kp) for the equilibrium NH4HS(s) ⇌ NH3(g) + H2S(g) is
