Prepare a graph of the data using time along the x axis and the running total of gas bubbles released on the y axis. Plot three curves on the same graph and label each with the temperature you recorded for each test tube. Before handing in your report, validate your results by comparing your graph results with at least one other team. Describe how the independent and dependent variable are related. Tell how the data supports this hypothesis.
Catalysts can be simple as elements or complex compounds.
Platinum and silver are two previous metals that act as catalysts in several inorganic reactions. Living cells use special catalysts that are complex proteins. These organic catalysts are called enzymes. Enzymes control cellular chemical reactions. In this investigation, you will experiment on both an enzyme and a simple inorganic catalyst.
