energy transfer, entropy, rate, and mechanism

INDEPENDENT DEFENSEINDEPENDENT TRANSFER

Mechanism from rate law

Observed rate law is rate=k[A]^2[B]. Proposed slow steps: I, A+B -> products; II, 2A+B -> intermediate. Assume an elementary rate-determining step.

  1. Elementary exponents match reactant molecularity.
  2. Observed order is two in A and one in B.
  3. Mechanism II matches the slow-step rate law.

Which proposal is consistent with the data?
