INVESTIGATING THE EFFECT OF HYDROGEN PEROXIDE CONCENTRATION ON CATALASE ANALYSIS TABLE SHOWING THE AMOUNT OF OXYGEN EVOLVED AT THE DIFFERENT CONCENTRATION OF HYDROGEN PEROXIDE. Concentration of Hydrogen Peroxide(M) Volume of Oxygen evolved(ml) Average Concentration of Oxygen Evolved (ml) 1.00 65.0 65.0 63.0 64.3 0.80 53.0 51.0 51.0 52.0 0.60 38.0 38.0 39.0 38.3 0.40 28.0 28.0 27.0 28.0 0.20 15.0 14.0 14.0 14.3 0.00 3.00 4.00 3.00 3.30 Calculating the Rate the Reaction. Rate (ml/s) =Volume of oxygen released (ml) Time(s) TABLE SHOWING THE RATE OF REACTION AT DIFFERENT CONCENTRATION OF HYDROGEN PEROXIDE Concentration Of Hydrogen Peroxide(M) Average Concentration of Oxygen Evolved Time (s) Rate (ml) 1.00 64.3 37.2 1.73 0.80 52.0 40.0 1.23 0.60 38.3 42.4 0.90 0.40 28.0 49.3 0.57 0.20 14.3 51.0 0.28 0.00 3.30 59.5 0.55 From the results, I have noticed that the volume of the products (Oxygen) decreases with decrease in the substrate (Hydrogen Peroxide) and so does the rate of the reaction. This is why on the graph the rate of the reaction is in proportion to the substrate concentration, ie. The...
