Amount of product gained or amount of reactant lost can be used to calculate the rate of reaction and draw graphs to represent its change.
These graphs can be produced from data sets acquired during practical experiments. Remember when calculating rate of reaction time should be in seconds.
The rate of reaction of an experiment is given by the gradient of its graph by finding the change in the mass or the volume of the reactants used or products used per unit time.
What would be an appropriate measurement for rate of reaction for this reaction: CaCO₃(s) + 2HCl(aq) → CaCl₂(aq) + H₂O(l) + CO₂(g) ?
Calculate an average rate of reaction for the graph shown.
Calculate the initial rate of reaction for the graph shown. The initial rate can be found by a drawing a straight line drawn from the beginning of the reaction. Give your answer in g/s.
Calculate the initial rate of reaction for the graph shown in cm³/s.
Why is initial rate of reaction higher than average rate of reaction?
Why are you calculating 'average' rate of reaction?
What should be on the axes of a graph showing rate of reaction?
What factors may influence this graph showing the reaction: Zn(s) + HCl(aq) --> H2 (g)+ ZnCl(aq) ?
What factors may influence this graph showing the reaction: 2NO(g) + O2(g) --> N2O4 (g) ?
What is the main factor that could change this graph from black to blue line for a reaction C₂H₄(l) + H₂O(l) → C₂H₅OH(l)?
How can rate of reaction be calculated by measuring the mass of a reactant mixture containing zinc and hydrochloric acid?
How can rate of reaction be calculated by measuring the volume of gas produced by a reactant mixture containing zinc and hydrochloric acid?
What would be an appropriate measurement for the rate of reaction in the reaction between calcium chloride and sulphuric acid?
Why do we observe plateau in many reaction rate graphs? Why would reaching plateau take less time at a higher temperature?
Draw a graph to show how the total volume of hydrogen gas produced would change throughout the course of a reaction between zinc and hydrochloric acid.

Draw a graph to show how the partial pressure of oxygen changes during a reaction 2NO(g) + O₂(g) → N₂O₄(g).
Draw a graph to show the impact of increasing temperature on the reaction between zinc and hydrochloric acid. There should be two lines on your graph, one for low temperature and one for high temperature.
