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

Explanation

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