How does the length of Magnesium affect the rate of reaction? Essay

How does the continuance of Magnesium affect the rate of reply? arousal Variables Magnesium skidHydrochloric acidOutcome Variable - Release of atomic number 1I have chosen to investigate whether the difference in length of aMagnesium ribbon, would change the speed in which the reaction surrounded byHydrochloric acid and Magnesium takes. We go forth measure this by timinghow enormous until the magnesium strip vanishes and there is no release ofHydrogen.Aim I am trying to find out whether the length of Magnesium fronts any alterations in the rate of reaction between Hydrochloric acid andMagnesium. I will be measuring this by timing how long it takes forthe magnesium to be no long-acting visible and there is no hydrogenreleased. foretelling I think that when Hydrochloric acid of the same volumecome in to contact with Magnesium of different lengths of ribbon,, therate if reaction for the longer strip would be far slower than the pitiableer one. I believe that this as the clash theory tells us thatmolecules collide which cause to react and merge to clear a compound.This reaction varies in speed depending on the amount of molecules inthe mixture and how much energy the molecules possess, which is whyheated molecules react fast than normal ones. So with the amount ofHydrochloric acid staying relatively the same hitherto the number ofMagnesium molecules increasing, the reaction will only take longer asthe molecules have to collide even more for the reaction to becomplete.Hypothesis If my fortune telling is to be proven correct, then the time taken to react to the longest strip of Magnesium would take thelongest and the short strip would take the least amount of time. Weshould also see from restate attempts at this experiment, that theaverages would also increase depending on the length of the Magnesiumribbon. gibe Variables I have chosen not change the volume of hydrochloricacid, and the comprehensiveness of acid will alter the amount and effectivenes s ofthe acid, which will fall in the rate of reaction speed up and cause anunfair experiment. I have also kept the magnesium strip the sameribbon, as if the width if the magnesium strip is changed, the surfacearea would become large and more molecules would be able to collideat one time, which would soused that the rate of reaction would befaster.Preliminary Work I have... ...unt of timetaken to perform the experiment and would give me the opportunity formore psychometric tests to be taken and more data to be retrieved.However, the tests that were performed were a fair test as the methodused was very simple, so error wasnt a large factor. This meant thatthe solution could react without being tampered with. Although, on do the second attempt for the 5cm strip, the tube wasaccidentally split by passers by, so we had to stop the time andrecord the time thus far. This could be the cause for the anomalieswithin the results and if I were to do it again, I would expect theresults to be greatly different.Due to the amount of stopwatches used in the experiment, we were ableto get the choose time for each test tube, which was easier forrecording than just using one, which I did during the preliminaryexperiment.Conclusion In conclusion, I found out that my prediction was rightand that the longer strip took a comparatively longer reaction timethan the short two centimetre strip. This can be seen from the differentiate gathered, which I believed to be accurate and would appearagain if this experiment were to be performed once more.
