State two reactions between non-metallic oxides and oxygen which take place in catalytic converter.

Explanation

`SO_(2)` on oxidation in presence of `V_(2)O_(5)` or platinum gives `SO_(3)`. This reaction takes place in the catalytic converter of automobiles.
`2SO_(2)+O_(2)overset(V_2O_2)underset((or Pt))rarr2SO_(3)`
Carbon monoxide which is a major constituent of automobile exhaust gets converted to `CO_(2)` in the catalytic converter of automobile engines.
`2CO+O_(2)rarr2CO_(2)`
