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?
