# Atmospheric chemistry - how to find a wavelength

Recently, it has been found that Cl2 can be released to the atmosphere in the marine boundary layer through mechanisms that oxidize chloride (Cl-) in sea salt aerosol. The Cl2 is unreactive at night and can build up to significant levels. Upon sunrise, Cl2 will photolyze, releasing very reactive Cl atom radicals according to the reaction: Cl2 + hv → Cl. + Cl.
a) If the bond energy of the Cl-Cl bond is 243 kJ/mole, calculate the maximum wavelength of light(in nm) that would dissociate the molecule

how would i do that can someone help plz

We can not help you unless you show some effort first. What thoughts/ideas do you have?
