Question

chemical reaction rates:

1) Choose the option below that shows the equation that relates the rate of consumption of H+ and the rate of formation of Br2 for the given reaction.

5Br−(aq)+BrO−3(aq)+6H+(aq)→3Br2(aq)+3H2O(l)

Answers

6Δ[H+]Δt=3Δ[Br2]Δt

−16Δ[H+]Δt=13Δ[Br2]Δt

16Δ[H+]Δt=13Δ[Br2]Δt

−6Δ[H+]Δt=3Δ[Br2]Δt
