I'm currently doing an EEI with catalase and hydrogen peroxide. I'm just wondering about the effects of increasing the temperature of the catalase and h2o2. For example, if I get 50mL of oxygen produced when both are at 40°C and the reaction occurs for 8 seconds. If I decrease the temperature to 30°C, 20°C and 10°C what should I expect to happen with the time and amount of oxygen produced? The same goes for if I increase it to 50°C and 60°C. Should the amount of oxygen being produced form a parabolic relationship, peaking at 40°C, or will there simply be no oxygen produced at certain temperatures? Temperature is one of our three variables being tested, the other two being the concentration of h2o2 and catalase. I have calculated the theoretical yield and our actual yields are very close. I was not able to calculate the time the reaction should occur for with the catalase concentrations increasing however I would like to have some calculations for the temperatures. Thanks.
