Problem Details

A reaction mechanism for ozone depletion in the stratosphere is

CF3Cl + UV Light → CF3 + Cl

Cl + O3 → ClO + O2

O3 + UV light → O 2 + O

ClO + O → Cl + O 2

CF+ Cl → CF3Cl

Identify all catalysts and intermediates

a) There are no catalysts but CF3, Cl, ClO, and O are intermediates

b) UV Light is a catalyst and CF3, Cl, ClO, and O are intermediates

c) CF3Cl is a catalyst and CF3, Cl, ClO, and O are intermediates

d) O3 is catalyst and CF3Cl, CF3, and Cl are intermediates

e) CF3Cl is a catalyst, CF3, Cl, ClO, O, and O2 are intermediates

What is the overall reaction for the mechanism given in the preceding question?

a) 2O3 + UV Light → 3O2

b) 2O3 + 2Cl → 2O2 + 2ClO

c) O3 + CF3Cl → O2 + ClO + CF3

d) 2O+ 2ClO + 2CF3 → 3O2 + 2CF3Cl

e) O3 + ClO → 2O2 + Cl
