If the molarity of the acid concentration is doubled, the rate of reaction will double.
This is because the particles are closer together in a concentrated solution.
RATE OF REACTION BETWEEN HYDROCHLORIC ACID AND CALCIUM CARBONATE LOW CONCENTRATION HIGH CONCENTRATION I think that during our experiment, the higher the molarity of acid the quicker the rate of reaction will be, I think this because of the collision theory.
If the solution is made more concentrated, there will be more particles in the solution.
We saw that this reacted too quickly as we used 10 second intervals and we couldn't get 6 results this is because our burette could only hold 100cm³ of water, which would make our results reliable.
We then decreased the amount of Calcium Carbonate to 1g and kept the same 25cm³ of 3 molar hydrochloric acid and 10 second intervals.Therefore, because they are closer the particles will collide more often.The more often they collide the more chance they have of producing a productive reaction.This makes collisions between important molecules more likely and will collide more often.At the beginning of the reaction, there are lots of reactants particles (and no products).This is because for the Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid In this piece of coursework, I will study how concentration affects the rate of reaction.I will do so by timing the reaction of Sodium Thiosulphate with an acid.Rate of reaction between Hydrochloric Acid and Calcium Carbonate Calcium carbonate reacts with hydrochloric acid to form carbon dioxide gas.One way of following the rate of reaction at which it reacts is to measure the volume of carbon dioxide produced at certain time intervals during the reaction.Variables: The concentration of Sodium Thiosulphate will be changed throughout the investigation and this makes it the independent variable in my investigation.In my investigation the dependent variable will be the time it takes for the reaction between Sodium Thiosulphate and Hydrochloric acid to take place.
