Calcuate K at 300 decrees C?
Ammonium chloride is sometimes used as a flux in soldering because it decomposes upon heating: NH 4 Cl(s) (arrow to right and arrow to left) NH 3(g) + HCl(g)
The HCI formed removes oxide films from metal to be soldered. In a certain equilibrium system at 300 degrees C, 8.2 g of NH 4 CI is present. The partial pressures of NH3 and HCI are 2.0 atm and 5.0 atm, respectively. Calculate K at 300 degrees C

K = (products / reactants) raised to their respective powers based on coefficients in balanced chemical equation.
Note that solids and liquids are not included in K expression.
K = [NH3] [HCl]
K = [2.0] / [5.0]
K = 0.4
Hope that's correct.Source(s): 1 year of General Chemistry @ research university
