Rates of Reaction Experiment :: GCSE Chemistry Coursework Investigation
Rates of Reaction Experiment INTRODUCTIONThis examine is called straddles of reaction, I will be partaking inthis experiment to find out what factors effect the rate ofreaction between magnesium (strips) and hydrochloric tart. Each timeI repeat the experiment, I will be adding 0.5 moles of hydrochloricacid and recording the volume of gas given out during the testing andrecord the time it takes to give the reaction needed. A reaction istaken place within the experiment because there is a collision ofparticles in each element. When these two elements collide with each another(prenominal) they form a chemical reaction ( a change which is irreversible)we know this because a gas is given of too file a change, this is whywe record the amount of gas given off to show when the reactions takesplace and how big of a change it has made.WORD EQUATIONMagnesium + Hydrochloric Acid Magnesium Chloride + Hydrogen AcidCHEMICAL EQUATION Mg + 2HCl H2 + MgCl2 activation energy is the minimum amoun t of energy, which the particlesmust have in order to react.There are five factors, which can make a difference to the rate of areaction.*1* The surface of the element*2* Catalyst, the amount of the substance*3* The concentration of the element*4* Temperature, due the heat of the atmosphere*5* Pressure pronounced to the substanceWhen a reaction takes place, the substances employ are called reactantsand the substances produced are called mathematical products. Because the amount ofproducts existence produced are increasing the number of reactants are orshould be decreasing.To calculate if and how well products are increasing and reactants aredecreasing we use a number of ways, we firstly find out how much ofthe reactant(s) is being used up and how much product(s) we aregaining from this in a set time.FORMULARS TO SOLVE THIS*** How much reactant is being used up***Amount of reactant being used upReaction rate = Time taken***How much products being produced in a set time***Amount of product formedReaction rate = Time takenA reaction can only take place when a successful collision isoccurred, so for a reaction to take place two different elements haveto concur with each other, this depends on the amount of atoms andenergy in the two elements, this is called a successful collision. Achemical reaction can only take place when two different elementscollide with each other.There are other methods to measure the rate (speed) of reaction.Precipitation observe a marker through the solution and predict howlong it takes to vanish.A change in mass a mass balance can only be carried out during the
