Multiple Choice

A proposed mechanism for the reaction CL₂(g) + CHCl₃(g) $\rightarrow$ HCl(g) + CCL₄(g) in the atmosphere is:
Step 1: CL₂ (g) $\rightarrow$ 2 Cl(g) (very fast, reversible)
Step 2: Cl(g) +CHCl₃ (g) $\rightarrow$ HCl(g) + CCl₃(g) (slow)
Step 3: Cl(g) + CCl₃ (g) $\rightarrow$ CCL₄(g) (fast) What is the rate law for the overall reaction?

• A)k[Cl₂]
• B)k[Cl₂][CHCl₃]
• C)k[CHCl₃][Cl₂]²
• D)k[CHCl₃][Cl₂]^1/2
• E)k[Cl][CCl₃]
