Laboratory Report: Factors affecting reaction rates Essay Essay
A: Effect of Concentration: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant, the faster the rate of reaction. Materials: MM hydrochloric acid solution, magnesium wire, distilled water, 4 test- tubes, misunderstandings. Procedure:1)ml MM hydrochloric acid solution is poured into a test-tube using a measuring cylinder. )A CM length of magnesium wire is added to the acid, and the stopwatch is started simultaneously.
The time it takes for the magnesium to disappear into solution is recorded. This time is recorded in the results table. 3)The test-tube is rinsed thoroughly and step
This means that the reaction rate will be affected, but not by a lot. ;The size of the magnesium wire is not equal. This will also affect the consistency 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 c Ion.
