Investigating The Affect of Concentration on The Rate of Reaction :: GCSE Chemistry Coursework Investigation

Investigating The Affect of Concentration on The Rate of ReactionAim- To experience out if changing the concentration of the hydrochloricacid affects the volume of hitman released in 5 minutes.Background InformationThe rate of reaction depends on quaternion things-1. Temperature2. Concentration3. Catalyst4. Size of particles/surface areaThe Collision systemThe collision theory explains the rates of reaction, the rate ofreaction depends on how practically and how strenuous the reacting particles clash with each other. The basic theory is that particles pick up tocollide with each other in order to react, but it is not that simple,as it also depends on how hard the particles collide. If the particlesdo not collide hard copious then they will not react, they will simply on the nose hit each other and bounce off.This means that even if I am not investigating the rate of reactionwhen the temperature is varyd, it will still have a big part to playin my experiment. If the temperatu re is different in the class livewhen I do each concentration of acid it whitethorn have a huge impact on myresults. To help lionise my results as accurate as possible I could takethe temperature of the room before I do each experiment.If the temperature in the room is beneath 20 C the particles will stillbe moving, but actually slowly. This would cause the react to be veryslow. At temperatures above 20 C the particles will be moving at a fixing speed.Low Concentration High Concentration activation EnergyActivation energy is the energy needed to start a reaction. Each subatomic particle has a certain amount of energy, when molecules collide theyhave to collide with more energy than they already have in order toreact this is called a successful collision. If the molecules collidebut do not create enough energy this is an unsuccessful collision andthe molecules do not react.I am going to focus on the concentration. If the concentration of thehydrochloric acid is increased, then so will the number of collisions.If the acid is more concentrated it means that at that place will be moreparticles in the same size distance compared to a diluted acid, thismeans collisions will be more presumable and more frequent as theparticles are closed together. appliance I Will Need- Conicle flask Glass syringe Bung talking to tube Marble chips(5 grams) Hydrochloric acid(50 cm ) Stop clockOther Apparatus that I May Need- Stand (to hold up gas syringe) Thermometer (to take the temperature of the room before do each concentration.) Weighing scales (to conjure out marble chips).MethodI am going to change the concentration of the hydrochloric acid to
