decomposition

In this equation one compound is changed into two compounds
This is an example of a decomposition reaction.

None of the elements change their oxidation numbers.

Hydrogen $H^(+1)$ remains +1 in Water. ( the products)
Sulfur $S^(+6)$ remains + 6 in Sulfur trioxide.
Oxygen $O^(-2)$ remains -2 in Oxygen.

Therefore it is not an oxidation reduction reaction.
