... Rates Of Reactions: Lab Report Introduction: In chemistry recently we have been doing the topic of Reactions. In this topic we have been learning about why elements react, how they react and what affects the reaction. For instance, temperature affects the speed of a reaction, and sometimes if there is any reaction at all. Aim: The aim of my experiment is to see how the factor of surface area affects the speed (rate) of a reaction between Hydrochloric Acid and Calcium Carbonate. Hypothesis: I know that the greater the surface area, the faster the reaction. Hence I predict that when I react Hydrochloric Acid with Calcium Carbonate, the Calcium Carbonate marbles will react slower than the Calcium Carbonate powder, as I think the powder has a higher surface area. The variables are as follows: Independent Variable: I shall be changing the surface area of the Calcium Carbonate to prove or disprove that it actually makes a difference
