Cl2(g) ↔ 2Cl(g)
Cl(g) + CHCl3 → HCl(g) + CCl3 (slow)
CCl3 + Cl(g) → CCl4(g) (fast)

Which of the following are true statements for the above mechanism ?

a) Cl(g) does not appear directly in the overall rate law


b) k1[Cl2] = k-12[Cl]


c) Cl(g) does not appear in the overall reaction


d) If this is a correct mechanism the observed law would be
Rate = k[Cl2]1/2[CHCl3]
