Can somepne please help me?!?

Question

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][CHCl3]

Answer 1

a, b and c, I reckon.
