Why will the reaction fail to work if the reactants are switched to 2‑bromonaphthalene and allyl alcohol while retaining the same phase transfer catalyst

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2

Answer explain why it is not possible to deduce a complete order of reactivity.
