I'm currently in high school and I'm doing a biology experiment with catalase reacting with hydrogen peroxide. I have measured the total amount of gas produced in terms of mL during the reaction which took place over 30 seconds.
Throughout the experiment I'm testing different concentrations of hydrogen peroxide - 3%, 2.4%, 1.8%, 1.2% and 0.6%.
If I would like to calculate the average rate of reaction do I simply divide the total amount of gas produced with time?
We were not allowed to use a pressure sensor by our teacher.
The Attempt at a Solution
Hydrogen Peroxide Concentration: 3%
Gas Produced: 60 mL of O2
Time: 30 sec
Rate of reaction: 2 mL O2/sec
Is this correct? Is the unit correct?
