Chemistry Laboratory Report: Factors affecting reaction rates

Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To canvass how the engrossment of a reactant affects the rate of reaction. Hypothesis: The more backbreaking the reactant, the fast-paced the rate of reaction. Materials: 2M hydrochloric acrimonious solution, atomic number 12 wire, distilled piss, 4 test-tubes, measuringcylinder. Procedure:1)10mL 2M hydrochloric back breaker solution is poured into a test-tube victimisation a measuring cylinder. 2)A 3cm aloofness of magnesium wire is added to the acid, and the stop watch is started simultaneously. The duration it takes for the magnesium to leave into solution is preserve. This time is recorded in the results table. 3)The test-tube is rinsed thoroughly and flavor 2 is perennial exploitation 8mL acid mixed with 2mL water system. 4)This is repeated for each acid-water mixture, as shown in Table 1. Results:Table 1Volume of HCl(ml)Volume of water (mL)Time taken (s)100418252736664120Calculatio ns: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 minginess of the hydrochloric acid provide growth its solubility. The high concentration of acid office there ar more reactants per molecule, making the reaction of the magnesium more effective.

Sources of fault in this experiment:?The dilution bidding of the hydrochloric acid is very crude. This means that the reaction rate will be affected, but non by a lot. ?The size of the magnesium wire is not equal. This will also affect the amity of the results, but again, not by a lot. ?The recording of the time may not be ! absolutely accurate. The experiment could be improved by reducing the sources of error i.e. handling the equipment as accurately as possible. Conclusion: The higher the concentration of the reactant, the higher the rate of reaction. If you wishing to get a full essay, hunting lodge it on our website: OrderEssay.net
