At high pressures and moderate temperatures nitric oxide gas disproportionates rapidly according to the reaction 3no(g) ⇌ n2o(g) + no2(g) a 1-liter vessel is pressurized with no(g) and maintained at a constant temperature until equilibrium is reached where k = 1.9×1016 (as expressed in terms of the concentrations of the gases in mol/l). at equilibrium, the amount of no(g) in the flask is found to be 7.5×10-6 mol. what is the equilibrium concentration of n2o(g)?
