3.5 Reaction Progress 3.5.1 Progress of a Reaction LO: I understand how to follow the progress of a reaction.

calcium + hydrochloric calcium + carbon + water Experiment: Equation: calcium + hydrochloric calcium + carbon + water carbonate acid chloride dioxide LO: I understand how to follow the progress of a reaction.

Volume of Carbon dioxide Graph: Volume of Carbon dioxide (cm3) Time (s) The steeper the line, the the rate of reaction. faster LO: I understand how to follow the progress of a reaction.

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

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.
