Problem 85E
Catalysis (Section)
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) Is this an example of homogeneous catalysis or heterogeneous catalysis?
