In doing some problems on elementary steps and rate laws....
2NO -> N202
2H2 -> 4H
N202 + H -> N20 + HO
2HO + 2H -> 2H20
H + N20 -> HO + N2
over= 2NO + 2H2 -> 2H20 + N2
question: why is 1) bimolecular when 2) is not and why is the rate law squared in 1 and not 2, 4?
probably a simple answer, but I just started reading this ...
thanks!
