The graph plotted to demonstrate the relationship between temperature and concentration of salicylic acid, Figure , has a high R 2 value of 0.9321, showing that the positive correlation between the independent and dependent variables is in fact strong. The calibration curve, Figure , also has a high R 2 value, 0.9761, proving it reliable for being the basis of all other carried out calculations, though the data points seem to plateau at the two highest concentrations of salicylic acid as opposed to increasing in a linear fashion. The data from the experiment itself is very precise as the concentration values calculated different trials of the same temperature do not vary by more than 0.00001mol/dm 3 ±0.00005, as can be seen in Table . This strong positive correlation obtained is supported by Collision Theory, since an increase in temperature increases the average kinetic energy and proportion of successful collisions amongst particles and increases the rate of hydrolysis, which in turn results in the increasing concentration of salicylic acid recorded. The graph in Figure , however, does not align with the theory that temperature and rate of hydrolysis have an exponential relationship, as the regression model is nearly linear. This may be a limitation of having chosen relatively lower temperatures for the independent values due to the scope of the experiment, as the graph of c=0.0004e 0.0029T becomes very steep at around c=4.50000×10 3 mol/dm 3 ±0.00005, which is a very value compared to the calculated concentrations of salicylic acid. It may also be a result of systematic errors.
