Hydrogen Chloride, HCl, decomposes at moderate temperatures according to the equation. 2HCl(g) <==> H2(g) + Cl2(g) The equilibrium mixture was found to contain 0.45mol of Cl2 in a 3-L vessel that started out with 4.00 mol of HCl . The temperature started and remained at 500K until equilibrium was reached. What is the Kc for the decomposition of HCl at this temperature?
