Kinetics- Kinetics of the Decomposition of Hydrogen Peroxide by Permanganate
Kinetics of the Decomposition of Hydrogen Peroxide by Permanganate
Description: Hydrogen peroxide is added to three beakers containing different concentrations of acidified potassium permanganate. The rate of evolution of oxygen depends on the concentration of the permanganate.
