11. Ozone naturally decomposes to oxygen via photodecomposition.
2 03(g) → 3 0₂(g)
AErxn=-284.4 kJ/mol, E,= 17.7 kJ/mol
The temperature of the lower stratosphere is typically around -80°C in winter, while increases to
around -60°C in the summer. How much faster is the photodecomposition of ozone in the summer
compared to the winter?
Ozone in the troposphere is formed by the following steps:
NO2 → NO + O
(1)
0 + 02 → 03
(2)
The first step is initiated by the absorption of visible light (NO, is a brown gas). Calculate the longest
wavelength required for step 1 at 25°C.
nm
Explain the relevance of the 1987 Montreal Protocol and its 2016 Kigali Amendment on regulating ozone depletion.
