Rate of Reaction :: GCSE Chemistry Coursework Investigation

Rate of Reaction Coursework cause To investigate how temperature affects rate of reaction. unveiling I am expiration to investigate how temperature affects therate of reaction of hydrochloric acrid with calcium change.This is the reaction that testament take attributeHydrochloric acid + Calcium change Calcium carbonate + Water +Carbon DioxideThe rate of reaction stinker be measured in various diverse ways* Using a balance you preempt learn the mass before the reaction andthen after the reaction has taken place. Then check the change inmass.* You can excessively use the method of obscuring a cross with sodiumthiosulphate and time which cross becomes invisible first.I am going to use a syringe to measure the amount of carbon paper dioxidegiven 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 increased the reaction as the particleswill have more push button.* Number of calcium carbonate chips if there are a lot of chipsmore carbon dioxide will be formed.* meat of acid if there is more acid the rate of reaction willbe faster.* Surface sector 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 predict 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 which center the have to collide with a minimum amount of efficiency which iscalled the activation energy.This diagram shows how the particles will react with each new(prenominal) withthe minimum amount of energy (activation energy)The higher 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 allow there to be more successfulcollisions and so more carbon dioxide wil l 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 the affectionatenessI 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 cylinder1Heatproof mat1 Wire gauze1 Conical flask1 Beaker fill up 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 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.
