    limiting gas

    NO (g) + O3 (g) --> NO2 (g) + O2 (g) Theoretical mole ratio = 1 : 1 : 1 : 1 n(NO) = 0.66/(16.00 + 1401) = 0.022 moles n(O3) = 0.72/(16.00 + 16.00 + 16.00) = 0.015 moles Therefore ozone is the limiting reagent. Since it is the limiting reagent (a chemical which is present in lesser amounts...
