Now it is time to design your own experiment to test how particle size (or surface area) affects reaction rate.

What would be your hypothesis for the experiment?

Hint: You are welcome to use the alka seltzer tablet and water reaction again to design this experiment that tests the effect of particle size on reaction rate. You are not required to use the alka seltzer experiment, you could design a different experiment but it must test particle size affect on reaction rate.

Hypothesis: If the particle size (or surface area) of the reactants is increased, then the reaction rate will also increase.
