A student investigated the rate of reaction between dilute hydrochloric acid and calcium carbonate. They compared the reaction using fine calcium carbonate powder to the reaction using large calcium carbonate marble chips of the same total mass. They measured the volume of carbon dioxide gas produced over a period of 150 seconds.
Their results are shown in the graph below.
Describe what the graph shows about the difference in the rate of reaction when using fine powder compared to large marble chips.
