Explain dissociate gaseous h-i to produce h atoms

Reference no: EM13535135

By using photons of specific wavelengths, chemists can dissociate gaseous H-I to produce H atoms with accurately known speeds. When H-I dissociates, the H atoms move away rapidly, whereas the relatively heavy I atoms move little. Average Bond Energies

(a) What is the longest wavelength (in nm) that can dissociate a molecule of H-I?

(b) If a photon of 253 nm is used, what is the excess energy (in J) over that needed for the dissociation?
