Ammonium bisulfide, NH4HS, forms ammonia,NH3, and hydrogensulfide, H2S, through thereaction

NH4HS(s)?NH3(g)+H2S(g)

This reaction has a Kp value of 0.120 at 25 ?C.


An empty 5.00-Lflask is charged with 0.250gof pure H2S(g), at 25?C.


What is the initial pressure ofH2S(g) in the flask?

23.4758 g of solid ammonium hydrogen sulfide is introduced into a 318.242-mL flask at 18.228 °C; the flask is sealed, and the system is allowed to reach equilibrium. What is the partial pressure of ammonia in this flask if Kp = 0.803 at 18.228 °C for the reaction

NH4HS(s) ⇌ NH3(g) + H2S(g)?

Report your answer to three significant figures.

please help with #2 and #3

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.
