I NEED SOMEONE TO HELP ME ANSWER ONE QUESTION

CHEM 415, Spring 2014, Atmospheric Chemistry Problem Set #2 (25 points possible) Reference Material: Finlayson-Pitts and Pitts Chapters 1 and 2; Jacobs Chapters 1 and 2 DUE DATE: May 8, 2014 before 5:00PM

(1) McKinney et al. (1997) report measurements of ClO and BrO in a chemically perturbed region of the stratosphere over Sweden. They observe that the production of BrO with decreasing solar zenith angle is so rapid that it implies the bromine atom source is very photolabile, likely BrCl, rather than BrONO2. Using the tables 4.28 and 4.30 that are printed on pages 113 and 115, respectively of your Finalayson-Pitts text book, calculate the lifetimes of BrCl and BrONO2 at a solar zenith angle of 86 to estimate how much faster BrCl photolysis would be compared to BrONO2 at 25 km.
