I'm looking for the mechanism for H2+Br2--2HBr with a rate law k[H2][Br2]^1/2.

Would the mechanism be:
Br2--2Br (slow)
Br+H2--HBr+H (fast)
HBr+H+Br--2HBr (fast)

I was going to explain this but I found this site that has your exact same question in it explained with other examples. See example 2. I can help you after you go through that site and still have trouble if you like. =) http://www.science.uwaterloo.ca/~cchieh/cact/c123/ratemech.html
