In the method of initial rates, only a small amount of reagent is used up (the change in concentration is small compared to the total concentration). The elapsed time is used to calculate the rate. Why is this more accurate than calculating the rate from the amount of time required to use up all of the reagent? (Hint: What happens to the rate as the concentration decreases?)
