Question

Research in your lab is focusing on the reaction: 2A + 2B C + D After performing many different experiments, you have determined that the rate law for this experiment is: rate k[A]2[B12. You and your graduate student have come up with six possible mechanisms for the reaction. How many of the following mechanisms are plausible mechanisms based on the rate law information you have? Mechanism 1 Mechanism 2 A+A+BC+Dslow Mechanism 3 Mechanism 4 A+BE slow fast F+B-> C + D fast slow fast fast Mechanism 5 Mechanism 6 fast slow fast slow fast O 3 O 2 O 1 4

Explanation / Answer

according to rate law,

rate = k2[A]^2[B]^2

mechanism1

A+A+B <===> E

Keq = [E]/[A][A][B]

E + B --> C+D

rate = k[E][B]

      = K*Keq[A][A][B][B]

rate = k2[A]^2[B]^2

k2 = k*Keq

answer: only mechanism-1 is possible
