How is rate of reaction measured
WebHow do you determine the rate of reaction? Well, what you actually want is the initial rate of reaction, when you’ve just combined the enzyme and substrate and the enzyme is catalyzing the reaction as fast as it can at that particular substrate concentration (because the reaction rate will eventually slow to zero as the substrate is used up). Web2 feb. 2024 · The rate of a chemical reaction is measured by the equation of change in concentration divided by time. This equation produces the units of Molarity/second or …
