The rate, or speed, at which chemical reaction occur can vary widely. A reaction rate is the change in concentration of a reactant or product with time.
If your initial concentration of hydrochloric acid (HCl) is 2.14 and the rate of reaction after 11.0 seconds is 0.012 M/s, what is your final concentration of HCl? (To check your answer, highlight the following: 2.01 M)
