Permanganate reacts with isopropyl alcohol in acidic medium as shown: 2MnO4- + C3H7OH + 6H+ → 2Mn2+ + C3H6O + 4H2O The kinetics of the reaction was determined by conducting runs of varying concentration of the reactants. Reaction time was measured as soon as the purple color of permanganate ion turned colorless. Kinetic data was shown below. Table 1.
