Question

In the air N2 and O2 occur naturally but they do not react to form oxides of nitrogen because

Answer 1

Answer:

Atomic nitrogen and atomic oxygen don't exist under "normal" conditions because each forms molecules N2 andO2. N2 is less reactive than O2 in most gaseous reactions because there is a strong triple bond between the atoms, all the valence electrons are in bonding orbitals, and more energy is needed to excite them.

Answer 2

The nitrogen and oxygen present in the air do not react from oxides of nitrogen in the air.

• In dinitrogen there is a nitrogen-nitrogen triple bond is present.
• The bond dissociation energy of the triple bond is very high.
• To make oxides of nitrogen this bond needs to break but very high energy is required to break this bond and this high amount of energy is not present in atmosphere.
• That's why the nitrogen and oxygen present in the air do not react from oxides of nitrogen in the air.
