The rate of the crystal violet/NaOH reaction is given by the following generalized rate law: Rate = k’[CV+]y where k’ is the pseudo rate constant defined by k’ = k [OH-]x , where k is the actual rate constant The actual rate constant can be calculated using the pseudo rate constant and the [OH-] present in the reaction mixture. If the reaction mixture is prepared by mixing 5.0 mL of 1.00 x 10-4 M crystal violet solution with 5.0 mL...
