Sulfur dioxide is used as ... Nettet29. jan. 2015 · When the mole ratio of O3/NO was greater than 1, products with a higher oxidation state (such as NO3, N2O5) were formed. The reactions between O3 and SO2 were weak; as such, it was difficult for O3 to oxidize SO2. This study used two kinetic mechanisms to evaluate the oxidation processes of NO and SO2 by ozone.
