In trichlorofluoromethane refrigerant (CCl3F, also known as Freon-11, R-11, or CFC-11), there are 3 C-Cl bonds. When these are photochemically broken by solar radiation in the stratosphere, free Cl atoms produced can catalytically destroy ozone, O3. If the C-Cl bond energy is 331 kJ/mol, calculate the energy in J to break one C-Cl bond, the frequency of light that corresponds to this photon energy, and the wavelength in nm of this light.
