Question

Solid NH 4 HS dissociates into NH 3 and H 2 S at a certain temperature; the equilibrium total pressure is 0.8 atm. If now NH 3 is pumped into the system so that its partial pressure becomes 1.6 atm, what will be the partial pressure (in atm) of H 2 S?

TestHub · Accepted Answer

Initially P NH3 = P H2S = 0.4 atm, so K p = 0.4 × 0.4 = 0.16 atm 2 After pumping, P NH3 = 1.6 atm P H2S = K p /P NH3 = 0.16/1.6 = 0.1 atm This is option (a).
