Question

o2 +hv =o +o o2 +o -o3 +m
can anyone explain​

Answer 1

Answer:

in the upper stratoshphere when sun's UV light reaches oxygen molecules (O₂) , the molecule undergoes homolytic cleavage forming two O free radicles

one of the radicle combines with another oxygen molecule (O₂) forming O₃ - ozone.

4.3⋅10-17cm3/s for the reaction O2(1Δ)+O2(1Δ)→O2(1Σ) +О2(3Σ) − (1), 2.8⋅10-13 cm3/s for the reactionO2(1Δ)+I(2P1/2)→O2(1Σ)+I(2P3/2) − (4) and 8.3⋅10-11 cm3/s for the reaction O2(1Σ) +I2→О2(3Σ)+2I − (2). Analysis of experiments shows that for the wide range of oxygen-iodine medium composition the dissociation occurs via the chain of reactions (1), (2), O2(1Δ)+I(2P3/2)→О2(3Σ)+I(2P1/2), (4) and via cascade process I2+I(2P1/2)→I2(v)+I(2P3/2), I2(v)+O2(1Δ)→2I+О2(3Σ).
