rate of reaction

Results of Rates of Reaction Experiments:

Throughout the experiments, I used 2 molar hydrochloric acid and 1gram of medium sized marble chips. This was to keep the tests fair. I varied the concentration of he hydrochloric acid by combining different amounts of water with different amounts of hydrochloric acid to decrease the molarity but keep the same amount of liquid in the equation.

Conclusion:

From analysis of the results I have recorded, I have come to the conclusion that the rate of reaction gets slower when the concentration of acid is weakened. This is proven by the graphs showing my data. This proves my prediction about the particle theory. I stated that when concentration was increased, the rate of reaction increased ...
