What is the unit of measurement for the rate of a chemical reaction?
The rate of a chemical reaction is typically expressed as the change in concentration over time. Therefore, its unit is the change in concentration (moles per cubic decimeter, Moles dm-3) divided by the change in time (seconds, sec-1). This results in a unit of moles per cubic decimeter per second (Moles dm-3 sec-1).
