In the experiment, we first used large pieces of potato and liver and then added 2ml of hydrogen peroxide. After, we used crushed liver and potato and then added 2ml of hydrogen peroxide. The crushed and large piece of liver both reacted quickly, while the crushed and large piece of potato reacted slowly. So my question is:

How does particle size (the size of the liver and potato) affect the rate of reaction?

The crushed peices have a lager surface area for the H2O2 to react with. Because both samples of liver reacted faster compared to the potato, that means the the H2O2 can not break down starches easily
