Different Variables Changing the Rate of ReactionTo show that different variables can multifariousness the rate ofreactions e.g. make them faster or slow-moving.Theory - That changing the variables in a reaction such as assimilation, temperature and surface bea will growth or decreasethe rate of reaction. This would happen because, if you convinced theconcentration of a solution to a higher concentration the rate ofreaction would increases, as on that point are more particles in the solutionwhich means the particles would collide more. As they are collidingmore, particles collide with the other substance fashioning the reactiontime much farter and greater. get-go Concentration = Slower Reaction High Concentration = FasterReactionLess Particles More ParticlesEquipment-Chronicle Flask Measuring CylinderGas syringe BeakerCalcium Carbonate StopwatchPestle and Mortar Boss and ClampHydrochloric Acid Clamp standBut and Tube Measuring ScalesSafety - As acid and Bunsens may be being us ed safety goggles shouldbe worn at all times and all hair laced back. As glass is being usedall bags should not be in the corridor and all should be careful whenhandling glass in drive of breakage. All science classroom safety rulesshould be followed to ensure a safe environment.Prediction - In our experiment we shall be changing the concentrationof the solution, making the solution weaker and stronger. I predictthat when the solution has been weakened by water to make it lessconcentrated 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 keep downs of particles the less amountcollisions with the calcium carbonate. Therefore when the hydrochloricacid is modify 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 th e 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 surface area, doing this will quicken or slow down theexperiment. To change the surface area put your calcium carbonate in apestle and mortar and grind down the chips into a powder, small chipsor ensue 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
