The indicator crystal violet, (V) reacts with NaOH (OH- ) according to the equation: CV(aq) + OH- (aq) → CV- (aq) (Violet) (Colorless) The rate law for the reaction is: Rate = k2 [CV] [NaOH]. In an experiment the concentration of NaOH exceeds that of the crystal violet by a factor of 1000 so the rate law becomes Rate = k1 [CV] where k1 = k2 [NaOH] . The following data were obtained for the reaction of crystal violet with...
