Answer to Question #7247 in Physical Chemistry for kyle
O2 molecules can dissociate to form O atoms by absorbing electromagnetic radiation. If it takes 489 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 molecules into O atoms?
