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) You would need to graph the results of your experiment. What variable would be on the x-axis?
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.
1 answer
The particle size/surface area of the reactant would be on the x-axis.
