The factors that affect the rate of reaction.

Method

1. Place the gas syringe into the clamp as shown in the diagram, making sure it is safely secure but not too tight as it can damage the equipment. Check the syringe for any leaks by pulling it and seeing if it goes back to 0. Make sure that is at 0 to begin with.
2. Measure out 50mls of hydrochloric acid in a conical flask.
3. Add 2cm of magnesium ribbon to the solution, place the bun on the top and start the timer.
4. Read how much CO has been given off in the gas syringe at 20 seconds and 40 seconds
5. Now repeat it with 25cm3 of HCl and 25cm3 of H0 and finally with 30cm of HCl and 20cm of H0

Results

Conclusion

The more concentrated the solution is, the more C0 is given off after a shorter time span. This means that the concentration of a solution affects the rate of reaction. However, to make sure that this presumption is correct I will do a further experiment, using a more varied range and repeats.
