Enzyme Action Over Time
graph of time vs product

We can calculate the rate of a reaction by measuring, over time, either the disappearance of substrate (as in our catalase example) or the appearance of product (as in the above graph). For example, on the graph above, what is the rate, in moles/second, over the interval from 0 to 10 seconds?

equation 1

so for this example, the rate would be

equation 2


Sample Problem
Calculate the rate in moles/second between 40 and 50 seconds.
