Chemistry Laboratory Report: Factors affecting reaction rates

Title: Factors affecting response ordinatesProcedure A: Effect of ConcentrationAim: To investigate how the immersion of a reactant affects the rate of reply. guess: The much concentrated the reactant, the fast the rate of reaction. Materials: 2M hydrochloric acrimonious event, nuclear number 12 equip, distilled piss, 4 test-tubes, measuringcylinder. Procedure:1)10mL 2M hydrochloric red-hot solvent is poured into a test-tube using a measuring cylinder. 2)A 3cm aloofness of atomic number 12 wire is added to the window pane, and the stopwatch is started simultaneously. The clip it takes for the milligram to leave into solution is recorded. This time is recorded in the results table. 3)The test-tube is rinsed thoroughly and flavor 2 is perennial using 8mL superman mixed with 2mL water. 4)This is repeated for separately dose-water mixture, as shown in remit 1. Results:Table 1Volume of HCl(ml)Volume of water (mL)Time interpreted (s)100418252736664120Calculations:Table 2Volume of HCl(ml)Volume of water (mL)Concentration (mol/L)1002821.6731.4641.2Discussions:The reaction between magnesium and hydrochloric acid:Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)Increasing the concentration of the hydrochloric acid will growth its solubility. The high concentration of acid mogul there ar more reactants per molecule, making the reaction of the magnesium more effective.

Sources of fault in this experiment:?The dilution process of the hydrochloric acid is very crude. This means that the reaction rate will be affected, and non by a lot. ?The size of the magnesium wire is not equal. This will withal affect the consistency of the results, but again, not by a lot. ?The recording of the time whitethorn not be short accurate. The experiment could be amend by reducing the sources of fallacy i.e. handling the equipment as accurately as possible. Conclusion: The higher(prenominal) the concentration of the reactant, the higher the rate of reaction. If you wishing to get a full essay, order it on our website: Ordercustompaper.com
