Now it is time to design your own experiment to test how particle size (or surface area) affects reaction rate. Answer the next seven questions about your experiment that tests the effect of particle size on reaction rate.
1) What variable would be on the y-axis of your graph?
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.
