The equilibrium constant (Kp) for the reaction below is 70.0 at 32 °C: NH4HS(s) <---> NH3(g) + H2S(g) A sample of NH4HS(s) is placed in an evacuated container and allowed to come to equilibrium. (You should calculate what the P is of all gases at this point) The partial pressure of H2S is then increased by the addition of 1.00 bar of H2S, and the system responds accordingly( shifts?). Calculate the partial pressure of every gas after such shift.
