Question

The oxidation of SO2 to SO3 is catalyzed by NO2. The reaction proceeds according to: NO2(g) + SO2(g) → NO(g) + SO3(g) 2 NO(g) + O2(g) → 2 NO2(g) (a) Show that the two reactions can be summed to give the overall oxidation of SO2 by O2 to give SO3. (b) Why do we consider NO2 a catalyst and not an intermediate in this reaction? (c) Is this an example of homogeneous catalysis or heterogeneous catalysis?
