4. Plot 1/1 (y-axis) against M (x-axis). Is the curve reasonably straight? Note: You did not start
timing all the reactions at the time you added the HC. This small difference in timing has an effect
on the shape of the curve. How could you correct for this?
5. Is the reaction rate directly proportional to the concentration?
6. What is the order of the reaction? How do you know?
