Rate of Reaction :: GCSE Chemistry Coursework Investigation

Rate of Reaction CourseworkAim To check over how temperature affects straddle of reaction.Introduction I am going to investigate how temperature affects therate of reaction of hydrochloric vinegarish with calcium carbonate.This is the reaction that impart take placeHydrochloric stinging + calcium ascorbic paneate Calcium Carbonate + Water +Carbon DioxideThe rate of reaction can be placardd in various different ways* Using a repose you can check the pack before the reaction and thusly after the reaction has taken place. Then check the change inmass.* You can in any case use the method of obscuring a cross with sodiumthiosulphate and time which cross becomes invisible first.I am going to use a spray to measure the amount of carbon dioxide wedded of at regular intervals. This is because it is accurate as thesmallest division on it is 1ml.The important variables are* Temperature if it is adjoind the reaction as the particles allow deport more qualification.* way out of calcium carbonate chips if there are a lot of chipsmore carbon dioxide will be formed.* Amount of astringent if there is more acid the rate of reaction willbe faster.* Surface area if the chips have a larger surface area then therate of reaction will be faster.PredictionI have chosen to investigate the affect of hydrochloric acid oncalcium carbonate chips. I bespeak that as the temperature of the acidincreases so will the rate of reaction. This is because for twosubstances to react they have to have a successful collision whichmeans the have to collide with a tokenish amount of energy which iscalled the activation energy.This diagram shows how the particles will react with each other withthe minimum amount of energy (activation energy)The high the temperature of the acid the faster the acid particleswill be moving around as theyll have more energy and there will morecollisions. This energy will also impart there to be more successfulcollisions and so more carbon dioxide will be formed in smaller amountof time. Therefore the rate of reaction will be faster.This diagram shows the reaction of particles with more energy from theheatI can also predict that the shape of my final graphical record of rate ofreaction and temperature will look like thisFrom this graph I can predict that as I increase the temperature by10C the rate of reaction will double.Apparatus 1 Bunsen burnerCalcium Carbonate chipsHydrochloric acid1 Syringe1 50ml measuring cylinder1Heatproof flavorless1 Wire gauze1 Conical flask1 Beaker filled with ice1 Thermometer1 clamp I chose to use the syringe as it has small divisions to help me makeRate of Reaction GCSE Chemistry Coursework InvestigationRate of Reaction CourseworkAim To investigate how temperature affects rate of reaction.Introduction I am going to investigate how temperature affects therate of reaction of hydrochloric acid with calcium carbonate.This is the reaction that will take placeHydrochloric acid + Calcium Carbonate Cal cium Carbonate + Water +Carbon DioxideThe rate of reaction can be measured in various different ways* Using a balance you can check the mass before the reaction andthen after the reaction has taken place.
