Effect Of Temperature essays Effect Of Temperature On The Rate Of A Reaction Between Hydrochloric Acid And Calcium Carbonate I am going to investigate the effect of temperature on the rate of a reaction between dilute hydrochloric acid and calcium carbonate. I will do this by heating dilute acid to a certain temperature and put a marble chip into the acid. I will then record the time it takes for the reaction to produce 30 ml of gas. Then I will repeat this process, keeping the concentration of the acid and surface area of the chip the same, only changing the temperature of the acid. Next I will repeat the experiment at 4 different temperatures and will take four sets of results and will also work out an average. The factors that effect the rate of reaction between hydrochloric acid and calcium carbonate are, the concentration of the dilute hydrochloric acid, the surface area of the marble chip and the temperature.

I will choose the same weight of chip for every set of results. I will then pour 40 ml of dilute hydrochloric acid into the flask (20 ml water, 20 ml hydrochloric acid), fill the trough to 3 quarters full of water and also fill the measuring cylinder to 3 quarters full of water. Next I will heat the flask of acid to a certain temperature as I am investigating the effect of temperature on a reaction. Once the dilute acid is at the desired temperature I will put the calcium carbonate chi ...
