Ammonium chloride is sometimes used as a flux in soldering because it decomposes on heating; NH4Cl (s) NH3 (g) + HCl (g) The HCl formed removed oxide films from metals to be soldered. In a certain equilibrium system at 400 ̊C, 22.6 g of NH4Cl is present; the partial pressures of NH3 and HCl are 2.5 atm and 4.5 atm, respectively. Calculate Kp at 400 ̊C.

Question
Ammonium chloride is sometimes used as a flux in soldering because it decomposes
on heating;
NH4Cl (s) NH3 (g) + HCl (g)
The HCl formed removed oxide films from metals to be soldered. In a certain
equilibrium system at 400 ̊C, 22.6 g of NH4Cl is present; the partial pressures of
NH3 and HCl are 2.5 atm and 4.5 atm, respectively. Calculate Kp at 400 ̊C.
