Question

$O_{2}$ undergoes photochemical dissociation into 1 normal oxygen atom (O) and more energetic oxygen $O_{2}$ . If (O) has 1.967 eV more energy than ( $O_{2}$ ) and normal dissociation energy of $O_{2}$ is 498 kJ mol $^{- 1}$ , the maximum wavelength effective for the photochemical dissociation of $O_{2}$ is:

174 nm
