Atmospheric chemistry - how to find a wavelength

Click For Summary
SUMMARY

The discussion focuses on the photolysis of chlorine gas (Cl2) in the marine boundary layer, specifically how it releases reactive chlorine radicals upon exposure to sunlight. The reaction Cl2 + hv → Cl. + Cl occurs when Cl2 is photolyzed, with a bond energy of 243 kJ/mole for the Cl-Cl bond. Participants engaged in problem-solving regarding the calculation of the maximum wavelength of light required to dissociate Cl2, emphasizing the importance of demonstrating effort in scientific inquiries.

PREREQUISITES
  • Understanding of atmospheric chemistry concepts
  • Knowledge of photolysis and its implications
  • Familiarity with bond energy calculations
  • Basic principles of wavelength and energy relationships

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 please

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


oke i actually was able to solve it thanks anyway
