Then with the catalyst that works fastest I will use it to see if a change in volume of the catalyst which change the rate of hydrogen peroxide breaking down. The equation for the decomposition of hydrogen peroxide is: 2H2O2 (aq) 2H2O (l) + O2 (g) (It is worth noting that the compounds used are catalyst and therefore they are not used up, nor do they play and part in the equation. They simply act to speed up the natural process of hydrogen peroxide decomposition.) The catalysts being used in this investigation are: Copper...
