My aim for this experiment is to find out how concentration affects the rate of reaction, when marble chips reacts with hydrochloric acid. :: GCSE Chemistry Coursework Investigation
My aim for this look into is to realize reveal how concentration affects the rate of reaction, when marble chips reacts with hydrochloric acid.Mansoor Khan An investigation to prove how concentration affects the 1rate of reaction.IntroductionMy aim for this taste is to meet out how concentration affectsthe rate of reaction, when marble chips reacts with hydrochloric acid.I am exit to use calcium coulombate (marble chips) to react withhydrochloric acid that bequeath recruit vitamin C dioxide liquid. The parfor this reaction isWord equation atomic number 20 change + Hydrochloric acid Calcium Chloride + CarbonDioxide + WaterSymbol equationCaCO 2HCl CaCl CO H OFor my experiment, I forget be experimenting on diametrical concentrationsof acid on marble chips. The other inconstants that I could contain chosenfor this particular experiment beTemperature- I thought active choosing this variable but was put off bythe difficulty of view the temperature. place area- I have not choose this because I did not want the factthat there were only three different sizes of marble chips, when Ineeded five results, and also it requires quite a capacious deviseerexperiment to find the right concentration of acid.PredictionI figure that if a high concentration of acid is used, the reaction lead be faster and thus resulting in more(prenominal)(prenominal) carbon dioxide beingnessproduced as gas. The weaker the concentration of acid, the slower thereaction and the less amount of carbon dioxide gas that will beproduced.The collision theory states that if particles in a effect haveenough vitality to break free from their real bonds to form latebonds they will, the amount of energy needed to form new bonds iscalled the activating energy. So if you increase the amount ofparticles in a settlement they will be more collisions.The collision theory also says that if the particles are eermoving and colliding with each other, when one particle collides withanot her, energy is transferred betwixt these particles and so energyis constantly gained or lost. The number of collisions with enoughenergy greater or equal to the activation energy, determines the rateof reaction.I expect that the 2 molar of hydrochloric acid when reacting withmarble chips will produce the closely carbon dioxide and in the leastamount of time, because they are more reactants in the response andmore particles that will collide with the reacting particles. Alsobecause this is the most concentrate resolvent that I am experimentingon there are more reacting particles of colliding around in thesolution this means that the will be more collisions amidst thereacting particles which is likely to cause a reaction, these reactingMy aim for this experiment is to find out how concentration affects the rate of reaction, when marble chips reacts with hydrochloric acid.

The equationfor this reaction isWord equationCalcium Carbonate + Hydrochloric acid Calcium Chloride + CarbonDioxide + WaterSymbol equationCaCO 2HCl CaCl CO H OFor my experiment, I will be experimenting on different concentrationsof acid on marble chips. The other variables that I could have chosenfor this particular experiment areTemperature- I thought about choosing this variable but was put off bythe difficulty of control the temperature.Surface area- I have not choose this because I did not like the factthat there were only three different sizes of marble chip s, when Ineeded five results, and also it requires quite a long preliminaryexperiment to find the right concentration of acid.PredictionI predict that if a high concentration of acid is used, the reactionwill be faster and thus resulting in more carbon dioxide beingproduced as gas. The weaker the concentration of acid, the slower thereaction and the less amount of carbon dioxide gas that will beproduced.The collision theory states that if particles in a solution haveenough energy to break free from their existing bonds to form newbonds they will, the amount of energy needed to form new bonds iscalled the activation energy. So if you increase the amount ofparticles in a solution they will be more collisions.The collision theory also says that if the particles are constantlymoving and colliding with each other, when one particle collides withanother, energy is transferred between these particles and so energyis constantly gained or lost. The number of collisions with enoughenergy grea ter or equal to the activation energy, determines the rateof reaction.I predict that the 2 molar of hydrochloric acid when reacting withmarble chips will produce the most carbon dioxide and in the leastamount of time, because they are more reactants in the solution andmore particles that will collide with the reacting particles. Alsobecause this is the most concentrated solution that I am experimentingon there are more reacting particles of colliding about in thesolution this means that the will be more collisions between thereacting particles which is likely to cause a reaction, these reacting
