There are many limitations in this experiment. For example, instead of pre-cooling the solutions, they were cooled while they were oscillating. Therefore, once the temperature was calculated and recorded, the solution itself was still reducing in temperature. This led to miscalculations which can lead to assumptions that my data and graph is incorrect.
The oscillation period increases due to cooler temperatures. Also, the information fitted into the Arhenius Equation shows that the activation energy is about 160 joules per mole. Joule per mole is a unit of energy per amount of material, in this case solution. Energy is measured in joules and the amount of material in moles.
