I'm doing an EEI on enzymes. I'm using catalase and hydrogen peroxide to produce oxygen. The oxygen is then collected into a measuring cylinder. My three variables are the concentration of catalase, concentration of hydrogen peroxide and the temperature of both. Increasing the concentration of catalase is supposed to speed up the reaction, which it has, but it is meant to decrease the time of the reaction, which it also has. I have calculated the theoretical yield and our actual yield is really close. My question is, how do you calculate the theoretical time the reaction should occur for. I asked my teacher if there is a way to do it and he said that there is however it is beyond a highschool kid. I get A+'s in chemistry and top the class, so I would really like to impress him by being able to calculate the theoretical time of each reaction.
Catalase concentrations are 5%, 10%..30% with 1% hydrogen peroxide, both kept at 40°C.

Thanks for your help
