Question

The equilibrium constant in terms of pressures, Kp, for the reaction NH3(g) + HI(g) NH4I(s) at 400 °C is 4.65. (a) If the partial pressure of ammonia is PNH3 = 0.985 atm and solid ammonium iodide is present, what is the equilibrium partial pressure of hydrogen iodide at 400 °C? (b) An excess of solid NH4I is added to a container filled with NH3 at 400 °C and a pressure of 1.16 atm. Calculate the pressures of NH3(g) and HI(g) reached at equilibrium.
