### HW 15.49

For 15.49b, why is [HOBr] included in the rate law? Shouldn't it be expressed in a different way (like we did in class today) because it is an intermediate?

My guess is that it's okay to write it in the second step rate law as [HOBr] because that step is not rate-limiting (it's not the slower step). Thus the intermediate [HOBr] is still not in the overall rate law.

Because it is not the rate determining step, we can write out the intermediate in the rate law for that specific step.
