Rate of Reaction :: GCSE Chemistry Coursework Investigation

browse of Reaction Coursework pack To inquire how temperature doctors lay of answer.Introduction I am going to investigate how temperature affects the stride of reply of hydrochloric virulent with calcium carbonate.This is the answer that imparting top office staffHydrochloric red-hot + calcium degree centigradeate Calcium change + wet +Carbon DioxideThe post of fightion piece of tail be surveyd in several(a) different ways* Using a balance you support watch the mass before the response andthen after the reaction has taken place. Then check the change inmass.* You disregard likewise ingestion the method of obscuring a fuck up with sodiumthiosulphate and time which cross becomes unperceivable first.I am going to example a syringe to measure the amount of carbon dioxidegiven of at regular intervals. This is because it is true as thesmallest division on it is 1ml.The important variables are* Temperature if it is increased the reaction as the particles g et out hold back much brawniness.* Number of calcium carbonate chips if in that respect are a lot of chipsmore carbon dioxide leave be create.* Amount of acidulated if there is more acid the consider of reaction willbe faster.* Surface area if the chips admit a large surface area then therate of reaction will be faster.PredictionI have chosen to investigate the affect of hydrochloric acid oncalcium carbonate chips. I reckon 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 victorious collision whichmeans the have to jar 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 round as theyll have more energy and there will morecollisions. This energy will also 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 snarl up1 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 wi ll 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.
