The rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time. The graph shows this for two reactions.

Rate (y axis) against concentration (x axis). The shape of each graph indicates whether the order of reaction for a particular reactant is zero, first or second order. Plot graphs of reaction rate ...

rate graphs can be produced. The volume of gas produced and the time taken need to be recorded. The rate of the same reaction could be monitored by measuring the change in the mass of reactants as ...
