Unformatted text preview: to equal
the production rate in any given year. The steady state concentration was calculated
as 0.624 ppb if the emissions continued at this rate indefinitely. Consider the
production of CFC12, which averaged 3.8
g/year for the same 20year
period. Use the same assumption regarding emissions equal to production.
(a) Calculate the steady state concentration of CFC12 if the 19701989 emissions
continued indefinitely.
(b) Which of these two CFCs emits more chlorine atoms to the atmosphere?
(c) Calculate the steady state mass of atmospheric chlorine from each of these
CFCs. Which of these CFCs would contribute more atmospheric chlo rine in
steady state if the emissions continued indefinitely? Solution #6: (a) Given data;...
