Question

Consider this overall reaction, which is experimentally
observed
to be second order in AB and zero order in C:
AB + C¡A + BC
Is the following mechanism valid for this reaction?
AB + AB ¡k1AB2 + A Slow
AB2 + C ¡k2AB + BC Fast

Accepted Answer

Hi everyone here we have a question asking us to consider the reaction below A plus. To see forms A C to the reaction is second order and A and zero order, and C. Is the proposed mechanism below Ballad to A plus B forms A to be slow, A to B plus two C forms A two plus Bc too fast and a two plus B C. Two forms A C two plus B fast. So let's see what we have here. We have a two B And we have b. c. two. So that leaves us with two a plus two C Forms AC two and this does not match our first reaction, so the overall does not match. So our answer is no. Thank you for watching. Bye.
