Solution: The carcinogen, CCl4 has been dumped into a holding pond. CCl4 will begin to decompose by the following reaction:      CCl4   → Cl3C•   + Cl•       ΔΕ for C—Cl bond = 327 kJ/mol Sunlight striking the earth has a frequency range from approximately 6.7×10 14 Hz to 4.4×10 14  Hz.If you assume the highest energy light must be the same energy of the Cl-Cl bond, can you expect sunlight alone to effect the decomposition?h = 6.63×10 -34 J•sec; c = 3.00 ×10 8  m/sec  

Problem

The carcinogen, CClhas been dumped into a holding pond. CClwill begin to decompose by the following reaction: 

     CCl4   → Cl3C•   + Cl•       ΔΕ for C—Cl bond = 327 kJ/mol

 

Sunlight striking the earth has a frequency range from approximately 6.7×10 14 Hz to 4.4×10 14  Hz.

If you assume the highest energy light must be the same energy of the Cl-Cl bond, can you expect sunlight alone to effect the decomposition?

h = 6.63×10 -34 J•sec; c = 3.00 ×10 8  m/sec
