C2 4.1 How fast?

• The rates of a reaction measures the speed of a reaction or how fast it is. The rate can be found by measuring how much of a reactant is used, or how much of a product is formed, and the time taken.
• Alternatively the rate can be found by measuring the time taken for a certain amount of a reactant to be used or product to be formed. These methods give the average rate for the time measured.

Rate of reaction = amount of reactant used divided by time or amount of…
