Freon-12 ( CF2Cl2 or dichlorodifluoromethane) is a refrigerant and aerosol propellant, which
is known to degrade ozone in the atmosphere through the formation of Cl when exposed to
photons ( hν ).
To determine reaction kinetics, you release 1000 g into a chamber exposed to sunlight and mea-
sure the declining concentration. Based on the data collected answer the following questions.
(a) What is the reaction order? Write out the rate expression for CF2Cl2 degradation.
(b) What is the k value or the reaction coefficient?
(c) After 30 days, how many moles of Cl have been produced?
