You have studied the gas-phase oxidation of hbr by o2:
4hbr(g)+o2(g)→2h2o(g)+2br2(g)
you find the reaction to be first order with respect to hbr and first order with respect to o2. you propose the following mechanism:
hbr(g)+o2(g)→hoobr(g)
hoobr(g)+hbr(g)→2hobr(g)
hobr(g)+hbr(g)→h2o(g)+br2(g)
based on the rate law, which step is rate determining?
