Chemistry Laboratory Report: Factors affecting reaction rates

Title: Factors affecting response ratesProcedure A: Effect of ConcentrationAim: To analyse how the engrossment of a reactant affects the rate of reaction. Hypothesis: The more hard 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 astringent solution is poured into a test-tube utilise a measuring cylinder. 2)A 3cm aloofness of atomic number 12 wire is added to the acid, and the stopwatch is started simultaneously. The succession it takes for the magnesium to leave into solution is enter. This time is recorded in the results table. 3)The test-tube is rinsed thoroughly and flavor 2 is perennial victimization 8mL acid mixed with 2mL urine. 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)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 dumbness of the hydrochloric acid entrust 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 act 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 physical struct ure 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, erect it on our website: BestEssayCheap.com
