When N2O5(g) is heated, it dissociates into N2O3(g) and O2(g) according to the reaction: N2O5(g) ⇌ N2O3(g) + O2(g) KC = 7.75 at a given temperature. The N2O3(g) dissociates to give N2O(g) and O2(g) according to the reaction: N2O3(g) ⇌ N2O(g) + O2(g) KC = 4.00 at a given temperature. When 4.00 mol of N2O5(g) is heated in a 1.00 L reaction vessel to this temperature, the concentration of O2(g) at equilibrium is 4.50 mol/L. Find the concentrations of all other species in the equilibrium system at this temperature.
