There is an error in the rate-determining step of the following proposed mechanism.
Slow step: CH3(g) + Cl2(g) – CH3(g) + HCl(9) and the rate rule is kz = [CH][CL]
Fast step: CH3(g) + Cl2(g) → CH2Cl(g) + Cr(g) and the rate rule is kz = [CH][CL]
Overall : CH2(g) + 2Cl2(g) - CH2Cl(g) + HCl(9) + Cr (9)
Which shows the correct rate-determining step for the mechanism?
O
CH (9) + 2Cl(9) - CH2Cl(9) + HCl(9) + C(g)
CHA(9) + Cl2(g) → CH3(g) + HCl(9) and the rate rule is ki = [CH][Cl]
CH (9) + Cl2(g) → CH3CI(9) + Cr(g) and the rate rule is ka = [CH][Cl]
CH3(9) + 2Cl2(g) → CH2Cl(g) + Cr(g) and the rate rule is kz = [CH][Cl]

Answer:

The steps with correct mechanism are given below:

C

1) CH₄(g) + Cl(g) → CH₃(g) + HCl(g) : This is a slow step.

The rate is given as: R1 = k₁[CH₄][Cl]  

2) CH₃(g) + Cl₂(g) → CH₃Cl(g) + Cl(g): This is a fast step.

The rate is given as: Rate = k₂[CH₃][Cl₂]  

∴ CH₄(g) + Cl₂(g) → CH₃Cl(g) + HCl(g)

Here, the slowest step will be the rate-determining step.
