Please see attachment for the problem.
Estimate the ODP (i.e.) Ozone Depletion potential for the following CFC alternatives relative to HCFC-22. and fill in the table with the ODP values. Justify the reasons for your ranking.
Compound kOH × 1012 cm3 molecule-1 s-1 ODP
CHF2Cl (HCFC-22) 1.2 exp (-1650/T) 0.05
CF3CH2F (HFC-134a) 1.7 exp (-1750/T)
CH3CFCl2 (HCFC-141a) 1.3 exp (-1600/T)
CF3Cl (CFC-11) - 1.0
CF3Br (H-1301) -
Ozone Depletion Potentials and the relationship between structure and ODP are discussed.
