We studied the effect of different concentrations of catalysts on the dissociation of Hydrogen Peroxide. Our hypothesis was that the highest concentration of enzymes would cause the filter disc to rise the fastest. The data we collected is as follows:

We have concluded that our hypothesis is supported by the data we gathered. The higher the concentration of enzyme, the faster the disc rose.
