Which of the following pairs of substance will react further with oxygen to form a higher oxide?

CO₂ and H₂O

NO and H₂O

CO and CO₂

SO₂ and NO

SO\(_2\)(Sulphur dioxide) can react further with oxygen to form SO\(_3\) (Sulphur trioxide) a higher oxide.

2SO\(_2\) + O\(_2\) → 2SO\(_3\)

NO (Nitric oxide) can also react further with oxygen to form NO\(_2\)( Nitrogen dioxide), a higher oxide.

2NO + O\(_2\) → 2NO\(_2\)
