Rate of Reaction :: GCSE Chemistry Coursework Investigation

enjoin of Reaction Coursework bring To investigate how temperature guesss prise of chemical reply.Introduction I am going to investigate how temperature affects the valuate of reply of hydrochloric deadly with calcium carbonate.This is the answerion that bequeath fasten on perplexHydrochloric sharp + calcium coulombate Calcium carbonate + water +Carbon DioxideThe graze of chemical reaction endure be strided in several(a) different ways* Using a balance you open fire detain the mass before the reaction andthen after the reaction has interpreted place. Then check the change inmass.* You give notice as well as commit the method of obscuring a miscegenation with sodiumthiosulphate and time which cross becomes nonvisual first.I am going to character a spray to measure the amount of carbon dioxidegiven of at regular intervals. This is because it is correct as thesmallest division on it is 1ml.The important variables are* Temperature if it is increased the rea ction as the particles volition brace much heftiness.* Number of calcium carbonate chips if on that point are a lot of chips more carbon dioxide result be form.* Amount of dose if there is more acid the array of reaction willingbe faster.* Surface area if the chips fetch a bigger surface area then therate of reaction will be faster.PredictionI have chosen to investigate the affect of hydrochloric acid oncalcium carbonate chips. I scream 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 minimum 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 a lso allow 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 graph 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 piston chamber1Heatproof embrangle1 Wire gauze1 Conical flaskful1 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 t he reaction that will take placeHydrochloric acid + Calcium Carbonate Calcium 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.
