Question

Give one example (equation) of a homogeneously catalysed reaction and name the catalyst.

Answer 1

\[\ce{2SO2{(g)} + O2_{(g)} ->[NO_{(g)}] 2 SO3_{(g)}}\]

Catalyst: Nitric oxide (NO)

In this reaction, both the reactants (SO₂​, O₂​) and the catalyst (NO) are present in the same gaseous phase; hence, it is an example of homogeneous catalysis.
