Hydrogen chloride gas can be rapidly formed by directly combining hydrogen gas and chlorine gas above 250 °C. If the Kc for the reaction is 121, and a mixture of H2, Cl2, and HCl at equilibrium contains 1.54×10-3 M H2 and 1.54×10-3 M Cl2, determine the concentration of HCl.
H2 (g) + Cl2 (g) ⇌ 2 HCl (g)
