Problem

What is the predicted rate law for the following mechanism?

Cl2(g) ⇌ 2Cl(g)                                    Fast

Cl(g) + CHCl3(g) → HCl(g) + CCl3(g)  Slow

Cl(g) + CCl3(g) → CCl4(g)                   Fast

a) Rate = k[Cl2][CHCl3]

b) Rate = k[Cl][CCl3]

c) Rate = k[Cl][Cl2][CHCl3]

d) Rate = k[Cl]1/2[Cl2][CHCl3]

e) Rate = k[Cl2]1/2[CHCl3]
