Ammonium hydrogen sulfide NH4HS(s) decomposes on heating according to the reaction NH4HS(s) ↔ NH3(g) + H2S(g) At 25 °C the equil
ibrium cnstant of the reaction is Kp = 0.11. What is the total pressure at that temperature in a flask that was initially partially filled with a sizeable amount of NH4HS(s)?
