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 CFC-12, which averaged 3.8 g/year for the same 20-year period. Use the same assumption regarding emissions equal to production. (a) Calculate the steady state concentration of CFC-12 if the 1970-1989 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;...
