The gas-phase reaction between Br2 and H2 to form HBr is
Chapter 15, Problem 15.65(choose chapter or problem)
The gas-phase reaction between Br2 and H2 to form HBr is assumed to proceed by the following mechanism: Br2 3:4 2Br Br 1 H2 3:4 HBr 1 H H 1 Br2 88n HBr 1 Br 2Br 88n Br2 a. Under what conditions does the rate law have the form rate 5 k9[Br2]? b. Under what conditions does the rate law have the form rate 5 k0[H2][Br2]1/2? c. Give expressions for k9 and k0 in terms of the rate constants used to define the mechanism.
