In the reaction,
`BrO_(3(aq))^(-)+5Br_((aq))^(-)+6H^(+)rarr3Br_(2(l))+3H_2O`
The rate of appearance of bromine (Bry) is related to rate of disappearance of bromide ions as

Options

A. `(d[Br_2])/(dt)`=-5/3(d[Br^(-)])/(dt)`
B. `(d[Br_2])/(dt)`=5/3(d[Br^(-)])/(dt)`
C. `(d[Br_2])/(dt)`=3/5(d[Br^(-)])/(dt)`
D. `(d[Br_2])/(dt)`=-3/5(d[Br^(-)])/(dt)`

Answer

D

Explanation

For the given reaction, `BrO_(3(aq))^(-) + 5Br_((aq))^(-) + 6H^(+)rarr 3Br_(2(l)) + 3H_2O_((l))`
Rate of reaction in terms of `Br_2` and `Br^(-)` is ,
rate=`1/3(d[Br_2])/(dt)=-1/5(d[Br^(-)])/(dt)" "therefore(d[Br_2])/(dt)=-3/5(d[Br^(-)])/(dt)`
