15.00 g solid NH4HS is introduced into 500 mL flask at 25°C

 

 

Suppose 15.00 g of solid ammonium hydrogen sulfide is introduced into a 500. -mL flask at 25°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 = 0.108 at 25°C for the following reaction?

NH4HS(s) ⇌ NH3(g) + H2S(g)

 

 

 

Kp = (P_NH3) (P_H2S)

( 참고 https://ywpop.tistory.com/7136 )

 

= (x) (x) = x^2 = 0.108

 

 

 

x = 0.108^(1/2)

= 0.32863

 

 

 

답: 0.329 atm
