If 3 mol of hydrogen chloride gas, HCl(g), is injected into a 1.50 L container at constant temperature, an equilibrium is established with the production of hydrogen gas (H2(g)) and chlorine gas (Cl2(g)). Find the equilibrium concentrations of all 3 species in the equilibrium mixture. The equilibrium constant (Keq) for this reaction is equal to 0.04.
