78. The chemical equilibrium of the reaction of decomposition of nitric oxide (IV) to nitric oxide (II) and oxygen was established at the following concentrations: [NO2] = 0.06 mol / l, [NO] = 0.24 mol / l and [O2] = 0.12 mol/l. Calculate the equilibrium constant of this reaction and the initial concentration of nitric oxide (IV).
