Answer to Question 1

CF2Cl2 (g) + h  CF2Cl (g) + Cl (g)
Cl (g) + O3 (g)  ClO (g) + O2 (g)
ClO (g) + h  Cl (g) + O (g)
Cl (g) + O3 (g)  ClO (g) + O2 (g)
----------------------------------------------------------------------------------------
C2F2Cl2 (g) + 2 O3 (g)  C2F2Cl (g) + ClO (g) + 2 O2 (g) + O (g)

Answer to Question 2

D
