74. The equilibrium of the homogeneous system 4HCl (g) O2 ↔ 2H2O (G) 2Cl2 (G) was established at the following concentrations of reactants: [H2O] P \u003d 0.14 mol / l; [Сl2]Р = 0.14 mol/l; [HCl]P = 0.20 mol/l; [O2]P = 0.32 mol/l. Calculate the initial concentrations of hydrogen chloride and oxygen.
