Investigation of the reaction between hydrochloric acid and marble chips :: GCSE Chemistry Coursework Investigation

Investigation of the reception between hydrochloric acid and stain chipsA chemical chemical reaction is when two or more message called reactants arechemically bonded to form a impudently product, as a result of the process,for a reaction to take place, the particles must start out abundant energizingenergy to collide and form new bonds , this is called a boffo striking. The minimum amount of energy needed for a madecollision is activation energy, which is The energy that an atomicsystem must acquire onward a process can occur. Chemical reaction is distinct to a physical reaction, chemical reaction are not correctableand results in a new product, however a physical reaction can beeasily reversed as it only varyd its state. The activation energy isable to loosen particles and enable them to from new bonds to producenew products. The faster the molecules are moving the bigger thechance of a successful collision, so the faster and stronger thereaction forget be , the more kinetic energy a reactant has the easierit is for the new bonds the collide and produce new bonds.Variables that you could changeConcentration of hydrochloric acidSurface world of chipsMass of marble chips blackmailTemperature gaudiness of hydrochloric acidTime allowed to measure oxygen given ofVolume of gas collectedVarying the concentrationHigher concentration will make the reaction stronger, there will bemore particles in the same volume so there are a plow more collisions,making the reaction faster and increasing the chance of a successfulcollision, lower concentration makes a weaker reaction, there will befewer particles so less chance of a collision.Varying the compelA higher amount of pull will bring particles proximate togethermaking the reaction faster as there will be more collision with theenergy, a lower amount of pressure will make the particles more spreadput , making the reaction slower and reducing the amount of collisionand energy.Varying the surface areaA bigg er surface area will result in the number of particles toincrease so there will be a higher chance of a collision increasingthe rate of reaction , so the reactant broke into smaller pieces wouldreact faster oppose to larger pieces.Varying the temperatureAn increased temperature will increase the speed of the particle sothey collide more frequent as they have more energy. therefrom thereaction will speed up, a decreased temperature will have less energyit will move slower, collide less a great deal slowing the reaction down.Varying the throttle valveIf I increase the catalyst , the particles will move a lot faster asthe catalyst speeds up the rate of reaction, because they are moving
