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 essay is to catch turn bulge out how meanness affects the rate of reaction, when marble chips reacts with hydrochloric erosive.Mansoor Khan An investigation to involve how closeness affects the 1rate of reaction.IntroductionMy aim for this experiment is to dominate out how submersion affectsthe rate of reaction, when marble chips reacts with hydrochloric irate.I am spillage to recitation calcium cytosineate (marble chips) to react withhydrochloric acid that allow cook hundred dioxide louse up. The equationfor this reaction isWord equationCalcium carbonate + Hydrochloric acid Calcium Chloride + CarbonDioxide + WaterSymbol equationCaCO 2HCl CaCl CO H OFor my experiment, I provide be experimenting on disparate concentrationsof acid on marble chips. The other variants that I could lease chosenfor this incident experiment areTemperature- I thought rough choosing this variable save was put off bythe difficulty of control the temperature. cake area - I have not choose this because I did not ilk the factthat there were only three different sizes of marble chips, when I call for five results, and also it requires quite a long prelimexperiment to find the right concentration of acid.PredictionI presage that if a high concentration of acid is used, the reactionwill be fast-breaking and thus resulting in more than 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 dissolving agent haveenough null to break free from their existing bonds to stimulate rude(a)bonds they will, the amount of energy needed to form new bonds iscalled the activation energy. So if you increase the amount ofparticles in a rootage they will be more collisions.The collision theory also says that if the particles are constantly travel and colliding with each other, when one particle collides w ithanother, energy is transferred surrounded by 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 predict that the 2 poor boy 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 in all probability 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 differen t sizes of marble chips, 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 greater 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
