O3 + O → 2O2

 

 

 

[1] Catalytic cycles for ozone loss: General Idea

.. O3 + X → XO + O2

+) O + XO → X + O2

------------------------

.. O3 + O → 2O2

 

> X is a catalyst.

 

 

 

[2] Nitrogen oxide (NOx) radicals

( NOx = NO, NO2 )

 

NO2 + hν → NO + O

 

.. NO + O3 → NO2 + O2

+) NO2 + O → NO + O2

-----------------------------

.. O3 + O → 2O2

[Stratospheric Ozone Depletion]

 

N2O + O → 2NO

 

The nitric oxide (NO) produced from N2O

destroys ozone in a series of reactions:

 

NO + O3 → NO2 + O2

O3 → O + O2

NO2 + O → NO + O2

 

For which net reaction is:

2O3 → 3O2
