Factors affecting the catalytic decomposition of Hydrogen peroxide Please refer to the additional files for tables/graphs. Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by which Hydrogen peroxide decomposes into water and Oxygen. …showed first 75 words of 3309 total…

The same scales ought to be used throughout the experiment, as different scales can be calibrated slightly differently and therefore have different sensitivities to different masses which may affect the results obtained.
