Rates of Reaction Experiment :: GCSE Chemistry Coursework Investigation

Rates of Reaction Experiment INTRODUCTIONThis examine is called gaits of response, I will be partaking inthis audition to find bring break what factors effect the rate ofreaction between magnesium (strips) and hydrochloric acid. Each timeI repeat the experiment, I will be adding 0.5 moles of hydrochloricacid and recording the volume of hit man given out during the exam andrecord the time it repletes to give the reaction needed. A reaction is taken smudge within the experiment because there is a collision ofparticles in separately element. When these two elements collide with each some other they form a chemical reaction ( a change which is irreversible)we know this because a gas is given of too show a change, this is whywe record the step 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 + atomic number 1 AcidCHEMICAL EQUATION Mg + 2HCl H2 + MgCl2Activation energy is the lower limit amount of energy, which the particlesmust have in order to react.There ar 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 used ar called reactantsand the substances produced argon called products. Because the amount ofproducts being 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 = metre taken***How much products being produced in a set time***Amou nt of product formedReaction rate = Time takenA reaction can only take place when a thriving 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 with(predicate) the solution and predict howlong it takes to vanish.A change in majority a mass balance can only be carried out during the
