Emma Richards Rate Of Reaction Between Marble Chips + Acid Aim: The aim of this experiment is to find out how different variables affect the rate at which the reaction will take place at between marble chips (CaCO) and hydrochloric acid (HCl). There are many variables that affect the rate of reaction such as; * Temperature * Concentration (pressure for gasses) * Catalysts * Surface Area In my experiment I will be testing how the change of concentration of hydrochloric acid makes an effect and changes the speed of the reaction. The reaction that will take place is: Hydrochloric Acid + Calcium Carbonate Calcium Chloride + Water + Carbon Dioxide (HCl) + (CaCO3) (CaCl2) + (H 2O) + (CO2) Hypothesis The more concentrated the acid is then the quicker the reaction will take place, because there will be more HCL particles than water particles for the marble chips to collide with and therefore react. More collisions between the...
