For part a, what i'm looking for is the rate law, and to determine the rate law, we're just looking for the thing that is the slowest.
00:09
So what we would expect is that the rate equals k, h2 to the first power, because there's a one in front of it in the elementary step, br minus to the first power, because there's the one in front of it in the elementary step.
00:24
But the problem is your rate law can only be expressed in terms of what your reactants are.
00:31
So for h2, not a problem because it is a reactant.
00:36
However, i can't do this for br minus because it is not a reactant.
00:41
In this case, it's either going to be a catalyst or an intermediate.
00:46
But what we can do is look in the first step.
00:49
We can end up creating br minus...
