The average bond enthalpies of the C-F and C-Cl bonds are 485 kJ/mol and 328 kJ/mol, respectively.

Question:

The average bond enthalpies of the C-F and C-Cl bonds are 485 kJ/mol and 328 kJ/mol, respectively.

(a) What is the maximum wavelength that a photon can possess and still have sufficient energy to break the C-F and C-Cl bonds, respectively? 

(b) Given the fact that O2, N2, and O in the upper atmosphere absorb most of the light with wavelengths shorter than 240 nm, would you expect the photodissociation of C-F bonds to be significant in the lower atmosphere?
