Which of the following expression is correct for the rate of reaction given below:
`5Br^(-)(Aq)+BrO_(3)^(-)(aq)+6H^(+)(aq) rarr 3Br_(2)(aq)+3H_(2)O(l)`

Options

A. `(Delta[Br^(-)])/(Delta t)=(Delta[H^(+)])/(Delta t)`
B. `(Delta[Br^(-)])/(Delta t)=5/6 (Delta[H^(+)])/(Delta t)`
C. `(Delta[Br^(-)])/(Delta t)=5/6 (Delta[H^(+)])/(Delta t)`
D. `(Delta[Br^(-)])/(Delta t)=6(Delta[H^(+)])/(Delta t)`

Answer

C

Explanation

`-1/5 (Delta[Br^(-)])/(Delta t)=-(Delta[BrO_(3)^(-)])/(Deltat)=-1/6 (Delta[H^(+)])/(Delta t)`
`(Delta[Br^(-)])/(Delta t)=5(Delta[BrO_(3)^(-)])/(Delta t)=5/6 (Delta[H^(+)])/(Delta t)`
