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
CF3 + 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) 2O3 + 2ClO + 2CF3 → 3O2 + 2CF3Cl
e) O3 + ClO → 2O2 + Cl
