The reaction between C25H30N3 (aq) and OH- (aq) is first order with respect to C25H30N3 (aq) in the presence of excess OH- (aq). A 10.0 mL sample of 0.10 M NaOH (aq) mixed with 10.0 mL of 2.5E-5 M C25H30N3 (aq). A 5.0 mL sample of the mixture is quickly transferred to a clean cuvette and placed in a spectrophotometer and reaction progress is measured. Approximately how did it take for 75% of the initial amount of C25H30N3 (aq) to react
