For the reaction,

4HBr+O₂----->2H₂0+2Br₂

rate=k[Hbr][O₂]

predict the mechanism of the reaction

I KNOW THE ANSWER BUT DONT KNOW HOW TO GET IT WITHOUT MEMORISING IT PLZ HELP!!

The predicted mechanism is

HBr +O2 -> HOOBr

HOOBr+ HBr -> 2HOBr

2HOBr + 2HBr -> 2H₂O+ 2Br2

The rate determining step is the first step
