      How is ozone produced in stratosphere?

    Answer:

      In stratosphere, a photon with a wavelength between 180 and 240 nm breaks the \[{{O}_{2}}\] molecule into atomic oxygen. \[{{O}_{2}}+hv\xrightarrow[UV-radiaion]{(180-240nm)}O+O\] Oxygen molecule captures the atomic oxygen to form an ozone molecule. \[M+{{O}_{2}}+O\to {{M}^{*}}+{{O}_{3}}+Heat\] Thus, overall balanced process of formation of ozone is: \[3{{O}_{2}}+hv\to 2{{O}_{3}}+Heat\]
