The effects of concentration on reaction rates

I could back this conclusion up by doing two things. Firstly, I could use my average time graph (graph 1) to work out what time any concentration would take to complete its reaction. This is especially because of the fact that all my results I tested followed a trend. What I can do is to look where any concentration level is in line with the line of best fit, and then I could take this point on the line of best fit and look to see where that point lines up with the time taken.

Patterns of Behaviour

5 mL of enzyme, and all of the trials were set up as two tubes to begin with. One tube had 3. 5 mL of water and 2. 0 mL of catechol, and the other had . 5 mL of enzyme. By keeping the enzyme and substrate separate, we were able to have more control over the starting point of the reaction, and were able to bring each individual component to the desired temperature before starting. The temperatures that our group tested were 37oC, 45oC, 50oC, 55oC, 65oC, and 75oC. Both our group and group A-4 tested 37 and 45 degrees. This allowed us to compare each group's results more accurately.
