The steeper the line, the the rate of reaction.
faster
LO: I understand how to follow the progress of a reaction.

4. 3.5.2 Calculating the Rate
LO: I understand how to calculate the average rate of a reaction.

5. The units depend on the quantity and the time:
The rate of reaction is the change in quantity of a reactant or product per unit of time.
change in quantity
Average rate =
change in time
The units depend on the quantity and the time:
Change in mass per minute =
g/min or g min-1
Change in volume per second =
cm3/s or cm3 s-1
LO: I understand how to calculate the average rate of a reaction.
