Rate of Chemical ReactionChemical Kinetics

How does the rate of disappearance of a reactant relate to the rate of appearance of a product in 5Br−+BrO3−+6H+→3Br2+3H2O5 Br^{-} + BrO_3^{-} + 6 H^{+} \rightarrow 3 Br_2 + 3 H_2O ?.

Expert Answer

−15d[Br−]dt=−d[BrO3−]dt=−16d[H+]dt=13d[Br2]dt=13d[H2O]dt-\frac{1}{5}\frac{d[Br^{-}]}{dt} = -\frac{d[BrO_3^{-}]}{dt} = -\frac{1}{6}\frac{d[H^{+}]}{dt} = \frac{1}{3}\frac{d[Br_2]}{dt} = \frac{1}{3}\frac{d[H_2O]}{dt}.
