The key thing you need to understand here is that chemical reactions depend on reactant particles bumping into each other (collision theory).The more concentrated a reactant is, the more likely it will be to bump into other reactants and product chemical change.Here is video of a quick lab performed to test this. In the video, varying concentrations of Na_2S_2O_3 are allowed to react with HCl. A timer is included in the video so you can see how the changing concentration changes the overall speed of the reaction!
