The stoichiometric equation for the oxid...

The stoichiometric equation for the oxidation of bromide ions by hydrogen peroxide in acid solution is
`2Br^(-) + H_2O_2 + 2H^(+) to Br_2+ 2H_2O`
Since the reaction does not occur in one stage, the rate equation does not correspond to this stoichiometric equation but is
rate = `k[H_2O_2][H^+][Br^-]`
What is the effect on the rate constant k of increasing the concentration of bromide ions ?
