Investigating how the concentration of reactants affects the rate of re

Investigating how the concentration of defendants affects the mark of chemical answerChemistry CourseworkThis taste is aimed at investigating how the concentration ofreactants affects the rate of receptionThe reception between hydrochloric acid and magnesium bequeath be apply toinvestigate how different concentrations of the acid affect the rateof reaction. The botch produced from the reaction will be measured andused to display the average rate of reaction.The rate of reaction is a measure of how fast a reaction is going andhow long it takes to complete. This rate is found by measuring the make sense of a reactant used up per unit of time or the tot of aproduct produced per unit of time. For this reaction, the product willbe measured, as this substance is the easiest and most accurate tomeasure.Scientific KnowledgeA reaction can be stimulated to go faster or laggard by varying thetemperature, the concentration of reactant and the surface area. Forthe magnesium and acid atoms to react to scotchher, they musti) Collide with each otherii) Have complete aptitude in the collision.1) The particles in the liquid move around continually. Above, an acid particle is about to collide with a magnesium atom.2) If the collision has enough energy, a reaction takes place. Magnesium chloride and hydrogen will be formed.3) If the collision does not have enough energy, no reaction occurs and the acid particle will bounce away again.Particles need to collide with enough velocity so that they react.During a chemical reaction, the particles have to collide with enoughenergy to eldest break the bonds and then to form the new bonds and therearranged electrons, so some of the particles do not have enoughenergy to react when... ...make a reaction take place. (The results from the second experimentwere used in order to get a more accurate data collection.)EvaluationFor future experiments, it must be noted that the fumble needs to beremoved from gas syringe afte r each test, as this was one of theproblems during the investigation. If the excess gas is not removed,the experiment begins and the results are completely out of range. Itwas felt that this experiment may have been easier with the aid ofthree people, as this would mean that in that respect were not so manyactivities fro each person to record or read. In order to get a moreaccurate result, having enter the measurements from the experiment,the results should have been averaged, instead of using only one set.For a mount conclusion to be confirmed, more tests should have beencarried out to provide enough evidence to support the argument.
