Different Variables Changing the Rate of Reaction :: Reaction Rates Science Gases Essays

Different Variables ever-changing the Rate of ReactionTo show that different variables can diverge the lay ofreactions e.g. make them faster or slower.Theory - That changing the variables in a reaction such asconcentration, temperature and protrude area go out change magnitude or decreasethe rate of reaction. This would happen because, if you changed theconcentration of a dissolvent to a higher concentration the rate ofreaction would increases, as in that respect are more particles in the ancestorwhich means the particles would collide more. As they are collidingmore, particles collide with the other substance do the reaction duration much farter and greater.Low meanness = Slower Reaction High Concentration = FasterReactionLess Particles More ParticlesEquipment-Chronicle Flask bill CylinderGas syringe BeakerCalcium Carbonate Stopwatch mold and Mortar Boss and ClampHydrochloric Acid Clamp stand however and Tube Measuring ScalesSafety - As acid and Bunsens may be being used refugety goggles shouldbe worn at on the whole times and any hair tied back. As grump is being usedall bags should not be in the corridor and all should be careful whenhandling glass in case of breakage. every(prenominal) science classroom safety rulesshould be followed to ensure a safe environment.Prediction - In our experiment we shall be changing the concentrationof the effect, making the solution weaker and stronger. I predictthat when the solution has been weakened by water supply to make it slightconcentrated the rate of reaction will be slower and weaker. This willhappen as there are less particles of hydrochloric acid reacting withthe calcium carbonate, the fewer amounts of particles the less amountcollisions with the calcium carbonate. so when the hydrochloricacid is strengthened by doubling the amount of hydrochloric acid andadding it with the equivalent amount of calcium carbonate the reaction willbe stronger and quicker. This will occur as there are more partic lesin the solution reacting with the calcium carbonate, as there are moreparticles in the solution the number in collisions will greatlyquickening the reaction time. method - After all equipment has been collected and set up (e.g.clamp stand), and all safety rules are followed. First weigh theamount of calcium carbonate you will use i.e. 4g. Then decide if youwill change the scratch area, doing this will quicken or slow down theexperiment. To change the surface area assign your calcium carbonate in a postage stamp and mortar and grind down the chips into a powder, small chipsor moderate it in the size given. After you have decide and carried outthis put the calcium carbonate into the chronicle flask. Then decideif you will change the concentration of the hydrochloric acid, to
