Consider this gas phase reaction ,
`Cl_(2)(g)+CHCl_(3)(g)toHCl(g)+C"C"l_(4)(g)`
The reaction is found experimentally to follow this rate law.
Rate`=k[CHCl_(3)][Cl_(2)]^(1//2)`
Based on this information , what conclusions can be drawn about this proposed mechanism?
step1:`Cl_(2)(g)to2Cl(g)`
Step2:`Cl_(2)(g)+CHCl_(3)(g)toHCL(g)+C"C"l_(3)(g)`
Step3:`Cl(g)+C"Cl"_(3)(g)toC"Cl"(g)`

A

Step 1 is the rate -determining step.

B

Step2 is the rate-determining Step.

C

Step3: is the rate -determining Step.

D

The rate-determining Step cannot be identified.
