Partial Pressure

#### Q. Ammonium bisulfide, NH4HS, forms ammonia, NH3, and hydrogen sulfide, H2S, through the reaction NH4HS(s) ⇌ NH3(g) + H2S(g) This reaction has a Kp value of 0.120 at 25 degrees C. In addition to the H2S already present in the flask, solid NH4HS is added until there is excess unreacted solid remaining. What is the mole fraction, x, of H2S in the gas mixture at equilibrium? Express your answer numerically.
