O₂ Molecules Can Dissociate to Form O Atoms by Absorbing

O₂ molecules can dissociate to form O atoms by absorbing electromagnetic radiation. If it takes 498 kJ to dissociate one mole of O₂ molecules to form two moles of O atoms, what is the frequency of the light that would have just enough energy to decompose a single O₂ molecule into O atoms?
