Question
The oxidation of SO2 to SO3 is accelerated 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, with appropriate coefficients, the two reactions
can be summed to give the overall oxidation of SO2
by O2 to give SO3. (b) Do we consider NO2 a catalyst or an
intermediate in this reaction? (c) Would you classify NO
as a catalyst or as an intermediate? (d) Is this an example
of homogeneous catalysis or heterogeneous catalysis?
