Reaction Mechanism
15. Chemical Kinetics / Reaction Mechanism / Problem 5

Consider the reaction below:

A + C2 → AC2

The reaction is first-order in A and first-order in C2.

Two mechanisms are proposed for the reaction: 

Mechanism 1 (single-step):

A + C2 → AC 

Mechanism 2:

B + C2 → BC + C slow

A + BC → AB + C fast

AB +  2 C → AC+ B fast

Are both mechanisms valid? If yes why?
