The rate law for the reaction BrO3 2(aq) 1 3SO3 22(aq) 88n Br2(aq) 1 3SO4 22(aq) is Rate 5 k[BrO3 2][SO3 22][H1] The first step in a proposed mechanism is SO3 22(aq) 1 H1(aq) 88n HSO3 2(aq) Fast The second step is rate determining. Write a possible second step for the mechanism.
C117 Chapter 13 Notes- Chemical Kinetics and Rates of Reactions 3-4-16 Homogeneous reaction- reactants in same phase, ie. combustions, acid/base Heterogeneous reaction- reactants in different phases, ie. oxidation of metal o Surface area can strongly influence rates Reaction rate- measure of how fast reaction occurs +2 +2 o Ex. 2 )6 + →3 2 )5 3 + 2 o −Δ o Reaction rate = Δ = average rate over time change Δ Negative if dealing with reactant, positive if product Depends on concentrations of reagents o If we make Δ
