The first order rate constant (K) for the reaction of OH with 4-CMPP go through maxima with increasing the concentration of cetyltrimethyl ammonium bromide(CTABr). Concentration of the surfactant can be analyzed in terms of Br ions in micellar pseudophases, which occur readily by aqueous CTABr and calculated second order rate constants.
