NH4HS(s) ⇌ NH3(g) + H2S(g) Kp = 0.108 at 25℃
Solid ammonium hydrogen sulfide, NH4HS,
dissociates appreciably even at room temperature
forming ammonia, NH3, and hydrogen sulfide, H2S, gases.
What is the total pressure at equilibrium
if solid NH4HS is placed in an evacuated container
and allowed to reach equilibrium?
Kp = 0.108 at 25℃.

ICE 도표를 작성하면,
NH4HS(s) ⇌ NH3(g) + H2S(g)
평형에서, ...... x ............ x
Kp = (P_NH3) (P_H2S) = (x) (x)
x^2 = 0.108
x = (0.108)^(1/2) = 0.329 atm
P_total = P_NH3 + P_H2S
= 0.329 + 0.329 = 0.658 atm
답: 0.658 atm
