Okay, for this problem we are given a proposed mechanism for the reaction and it has these three elementary steps as listed, one, two, and three.
00:10
We need to find the overall reaction for this.
00:14
So what we need to do is we go through and we cancel out things that are on opposite sides.
00:21
So these all cancel each other out.
00:25
All of our hbr's are additive, so 4hbr, we have one, two, three, four of those, plus the o2 goes to 2h2o plus 2br2.
00:43
And this should be all balanced, so 4h's, 4h's, 4br's, 4br's, 2os, and 2os.
00:49
So that's the overall reaction for this.
00:51
Okay, the next question is about intermediates.
00:54
Intermediates are things that appear first as a product and then are used up in a subsequent step...
