At 23°C, Kp = 0.075 for the equilibrium:

NH4HS (s) ↔ NH3 (g) + H2S (g)

A sample of solid NH4HS is placed in a closed vessel and allowed to equilibrate. Calculate the equilibrium partial pressure (atm) of ammonia, assuming that some solid NH4HS remains.

  • chemistry - ,

    ..........NH4HS ==> NH3 + H2S
    I..................0.......0
    Equil...............p.......p
    Kp = 0.075 = pNH3*pH2S
    0.075 = p^2
    p = sqrt(0.075) = ?

  • chemistry - ,

    0.27
