We have given, Total pressure at equilibrium = 2 atm. Constant temperature = NH4HS(s) \(\rightleftharpoons\)NH3(g) + H2S(g) Kp = \(\frac{P_{NH_3}\times P_{H_2S}}{P_{NH_4HS}}\) ∵ Partial pressure of solid substance is considered to be 1. ∴ Kp = \(P_{NH_3}\times P_{H_2S}\)  Kp = \((P_{NH_3})^2\) (From the...
