{time~taken}\) 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.

If the concentration of reactants is increased, there are more reactant particles moving together. There will be more collisions and so the reaction rate is increased. The higher the concentration ...

Key chemistry topics include concentration vs. time data; rate constants (k); reaction order ... activities and concepts aim to clarify the relationship between equations, graphs, and the molecular ...
