The photodissociation wavelength of ozone is 320 nm.  This means that ozone efficiently absorbs light below this wavelength and breaks apart according to the following photochemical reaction.

O₃ + hn à O₂ + O

Any excess energy above the dissociation energy will be carried away by the kinetic energy of

O₂ and O.  Assuming that the kinetic energy is shared equally by O₂ and O calculate the velocity

of O₂ and O when ozone is photodissociated by a photon with a wavelength of 250 nm.
