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

Different Variables Changing the Rate of ReactionTo memorialise that different variables can change the send ofreactions e.g. make them faster or slower.Theory - That changing the variables in a reaction such as dousing, temperature and surface area provide increase or decreasethe rate of reaction. This would excrete because, if you changed theconcentration of a solution to a higher concentration the rate ofreaction would increases, as in that location are more particles in the solutionwhich means the particles would collide more. As they are collidingmore, particles collide with the opposite substance making the reactiontime much farter and greater.Low soaking up = Slower Reaction High Concentration = FasterReaction slight Particles More ParticlesEquipment-Chronicle Flask Measuring CylinderGas spray BeakerCalcium Carbonate StopwatchPestle and Mortar Boss and hugHydrochloric Acid Clamp standBut and Tube Measuring Scales recourse - As acid and Bunsens may be being used caoutc houc goggles shouldbe worn at alone times and alone hair tied back. As glass is being usedall bags should not be in the corridor and all should be careful when discussion glass in case of breakage. All science classroom synthetic rubber rulesshould be followed to ensure a safe environment.Prediction - In our taste we shall be changing the concentrationof the solution, making the solution weaker and stronger. I callthat when the solution has been weakened by water to make it less heavy the rate of reaction will be slower and weaker. This willhappen as at that place are less particles of hydrochloric acid reacting withthe calcium change, the less amounts of particles the less amountcollisions with the calcium carbonate. Therefore when the hydrochloricacid is strengthened by doubling the amount of hydrochloric acid andadding it with the same amount of calcium carbonate the reaction willbe stronger and quicker. This will occur as there are more particlesin the solution reacting with the calcium carbonate, as there are moreparticles in the solution the number in collisions will greatlyquickening the reaction time.Method - by and by all equipment has been cool and set up (e.g.clamp stand), and all safety rules are followed. prime(prenominal) weigh theamount of calcium carbonate you will use i.e. 4g. thus decide if youwill change the surface area, doing this will quicken or slow big money theexperiment. To change the surface area put your calcium carbonate in apestle and mortar and grind down the chips into a powder, small chipsor leave it in the size given. After you have decide and carried outthis put the calcium carbonate into the score flask. Then decideif you will change the concentration of the hydrochloric acid, to
