Investigate the effect of temperature on the rate of reaction :: GCSE Chemistry Coursework Investigation

To investigate the effect of temperature on the rate of reactionBackground InformationChemical reactions abbreviate place all the fourth dimension at many different rates,some be incredibly fast like an explosion-where you get no time to go steady whats happening or like rusting which could take up years before theiron is completely rusted.The rate of reaction is extremely important because you need to realizehow long before the end of the session or you may not get results intime. In living organisms its vital that all the chemical reactionstake place at the rates which supply the cells with the things theyneed exactly when they need them.Reaction rates are also important in the chemical persistence as in anyindustrial process the ultimate purpose is to make money by producinguseful products. In the chemical industry this core its important tomake as a lot of the desired product as cheaply as possible which meansthat the rate of reaction must be fast enough to make as much o f theproduct as quickly as possible without risking overheating orexplosions and without costing too much How money hungry are we eh?Successful chemistry, whether microscopic or at a chemical plant,depends on controlling the rate of the ongoing reactions. In ordinance tounderstand what affects the rate of chemical reactions and how we cancontrol them we need to measure the rate of the reaction. The two waysto do this are measuring how quickly the reactants are used up or wecan observe how quickly products are formed. Once we have ameasurement for the reaction under one cook of conditions, we canchange them and make comparisons of the changing reaction rate underdifferent conditions.There are 3 ways to measure the rate of reaction. We can measure achange in mass, if the reaction involves a gas being given off. Themass disappearing can easily be metrical and recorded over a period oftime. Another way to see is by measuring the rate of precipitation.When an insoluble steadfast for ms as a solid in solution, the solutionwill gradually become more and more opaque. Paper with a mark on itcan be used and the time taken for the mark to become invisible can berecorded. Another way to measure the precipitation rate is to use alight rhythm and data logger to record the amount of light transmitted.Finally, the last way is to measure the volume of gas given off usinga spray but this can only be used when a gas is given off.The rate of reaction depends on four things temperature increases the
