Regulаr flights оf supersоnic аircrаft in the stratоsphere are of concern because such aircraft produce nitric oxide, NO, as a byproduct in the exhaust of their engines. Nitric oxide reacts with ozone, and it has been suggested that this could contribute to depletion of the ozone layer.   The reaction NO + O3 → NO2  + O2 is first order with respect to both NO and O3 with a rate constant of 2.20 x 107 L/mol/s.   What is the instantaneous rate of disappearance of NO when [NO] = 3.3 x 10–6 M and [O3] = 5.9 x 10–7 M?
