decomposition

Explanation:

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.
