Express the rate of the reaction between bromide and bromate ions in acid medium.

Explanation

The rection between bromide and bromate ions in acid medium is given by the equation,
`5Br_((aq))^(-)+BrO_(3(aq))^(-)+6H_((aq))^(+) to 3H_(2)O_(l)+3Br_(2(aq))`
The rate of the rection is expressed as,
Rate
`=-(1)/(5)(Delta[Br^(-)])/(Deltat)=-(Delta[BrO_(3)^(-)])/(Deltat)=-(1)/(6)(Delta[H^(+)])/(Deltat)=(1)/(3)(Delta[H_(2)O])/(dt)=(1)/(3)(Delta[Br_(2)])/(Deltat)`
