The Chlorination of vinyl chloride, C2H3Cl +Cl2-->C2H3Cl3, is believed to proceed by the following mechanism:

Question

Cl2 --(k1)--> 2Cl*
Cl* + C2H3Cl --k2--> C2H3Cl2*
C2H3Cl2* + Cl2 --k3--> C2H3Cl3 + Cl*
C2H3Cl2* + C2H3Cl2* --k4--> stable species

Derive the rate law expression for the chlorination of vinyl chloride based on this mechanism.

Answer 1

hrtht

Answer 2

k3(K1/K4)^(1/2)*[Cl2]^(3/2)
