The equilibrium constant in terms of pressures, Kp, for thereaction NH3(g) + HF(g) NH4F(s) at 25 °C is 10.2. (a) If thepartial pressure of ammonia is PNH3 = 0.553 atm (at equilibrium)and solid ammonium fluoride is present, what is the equilibriumpartial pressure in atm of hydrogen fluoride at 25 °C? An excess ofsolid NH4F is added to a container filled with NH3 at 25 °C and apressure of 1.09 atm. Calculate the pressures of NH3(g) and HF(g)reached at equilibrium in atm.
