The amount of energy given off in this very exothermic reaction is sufficient to cause the water to boil.
This is because more catalyst will have a greater surface area for the reaction to take place.
The chemical formula of hydrogen peroxide is h2o2, the chemical formula for oxygen is o2, and the chemical formula for water is h2o. If acidic manganese dioxide is used, hydrogen peroxide is oxidizzed to oxygen gas while manganese dioxide will be reduced to manganese +2 ion. The catalyst is in the same phase as the reaction mixture. By adding a catalyst to an aqueous solution of h 2 o 2 and recording the rate of reaction at specific time intervals, you can monitor the total volume of oxygen gas being produced. A short summary of this paper. To investigate the rate of a chemical reaction. Catalytic decomposition of hydrogen peroxide on manganese dioxide nanoparticles was studying under different experimental conditions such as ph (1, 6.5 and14) and at 15°c temp. This is because more catalyst will have a greater surface area for the reaction to take place. Hydrogen peroxide decomposes into water and oxygen as follows: Maximum concentration hydrogen peroxide would produce oxygen at a much faster rate.

H2o2(l) → h2o(l) + 1/2 o2(g) this occurs much too slowly to be monitored. Pour some aqueous hydrogen peroxide solution into a vertical flask In a decomposition reaction where hydrogen peroxide decomposes in the presence of manganese dioxide, how much of each (hydrogen peroxide and manganese dioxide) should be used to result in 50 ml of. The gas molecules of the water move rapidly producing a white cloud of steam. This is a decrease of 53%. This is why i predict that the rate of reaction will increase as the concentration of the manganese dioxide. This experiment examines the rate of production of oxygen gas from hydrogen peroxide using manganese dioxide as a catalyst.
