Assuming the NaOH stock solution is 0.097 M, what are the initial concentrations of crystal violet and hydroxide ion in a solution made up of4.0 mL of the NaOH stock solution diluted to 50 mL plus 50 mL of 1.00 X 10- 5 M Crystal Violet~n?

The reaction of a dye called "O'Hara Scarlet" with 2.00 X 10- 3 M sodium hydroxide solution is found to occur with a pseudo rate constant ql of 0.84. With 4.00 X 10- 3 M sodium hydroxide, q2 is 3.36. Assuming the reaction is first order with respect to the dye, what are nand k for this reaction?
