Consider the following mechanism for the oxidation of bromide ions by hydrogen peroxide in aqueous acid solution. H+ + H2O2 ? H3O2+ (rapid equilibrium) H3O2+ + Br- ? HOBr + H2O (slow) HOBr+H+ +Br- ?Br2 +H2O(fast) Which rate law is consistent with this mechanism? k[Br-][H+]-1[H2O2]-1 k[H+][H2O2][Br-] k[H+][H2O2] k[HOBr][H+][Br-]
