The answer is SO3. Reaction with molecular oxygen.pdf

The answer is SO3. Reaction with molecular oxygen is an oxidation reaction.
During that reaction oxidation number of the oxidized element would increase. If the element is
already in the highest oxidation state, then the reaction would not take place. In the giving
molecules oxidation states are: NO, nitrogen is +2 N2O, nitrogen is +1 SO3, sulfur is +6 P4O6,
phosphorus is +3 Highest oxidation state for nitrogen and phosphorus is +5, so they could be
oxidized further in the given compounds. The sulfur is already in its highest oxidation state +6,
so SO3 could not react with oxygen.
