Investigating how the concentration of reactants affects the rate of responseChemistry CourseworkThis experiment is aimed at investigating how the concentration ofreactants affects the rate of reactionThe reaction between hydrochloric acid and magnesium allow for be used toinvestigate how different concentrations of the acid affect the rateof reaction. The heavy weapon produced from the reaction go forth 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 dogged it takes to complete. This rate is found by measuring theamount of a reactant used up per social unit of time or the amount 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 slower by varying thetemperature, the concentration of reactant and the surface area. Forthe magnesium and acid particles to react together, they musti) Collide with each otherii) withstand becoming energy 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 first good fortune 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 base experimentwere used in order to get a more accurate data collection.)EvaluationFor future experiments, it must be noted that the gas needs to beremoved from ga s syringe after 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 exclusively out of range. Itwas felt that this experiment may have been easier with the aid ofthree people, as this would mean that there were not so manyactivities fro each psyche to record or read. In order to get a moreaccurate result, having recorded the measurements from the experiment,the results should have been averaged, instead of using only one set.For a full conclusion to be confirmed, more tests should have beencarried out to provide enough evidence to support the argument.
