title Factors affecting reaction ratesProcedure A Effect of ConcentrationAim To investigate how the concentration of a reactant affects the rate of reaction.Hypothesis The to a greater extent concentrated the reactant, the faster the rate of reaction.Materials 2M hydrochloric venomous solution, magnesium wire, distilled water, 4 test-tubes, measuringcylinder.Procedure1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder.2)A 3cm length of magnesium wire is added to the acid, and the stopwatch is started simultaneously. The time it takes for the magnesium to vaporize into solution is recorded. This time is recorded in the results table.3)The test-tube is rinsed thoroughly and step 2 is repeated using 8mL acid mixed with 2mL water.4)This is repeated for each acid-water mixture, as shown in Table 1.Sources of error in this look intoThe dilution work at of the hydrochloric acid is very crude. This means that the reaction rate will be affected, si mply not by a lot.The size of the magnesium wire is not equal. This will also affect theconsistency 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. remnant The higher the concentration of the reactant, the higher the rate of reaction.
