In undertaking the experiment, the hypothesis was formed "if the number of reacted Alka Seltzer tablets increases, then the maximum reaction rate will increase". When graphing the relationship between the maximum reaction rate and the number of Alka Seltzer tablets reacting, Graph 7 produced a line of best fit with a constant increasing slope that passed through the origin (0.0). This is characteristic of linear graphs, which have the general equation, y=mx, where m is the slope, a constant term, and y and x are variable variables that are directly proportional (i.e. y ∝x). It can therefore be deduced that Graph 7 is a linear graph, and that there is a linear relationship between the maximum reaction rate and the number of Alka Seltzer tablets, where they are directly proportional. That is, as the number of Alka Seltzer tablets increased, the maximum reaction rate increased, supporting the hypothesis. Because the true value of the maximum reaction rate per Alka Seltzer tablet was not known and no value was available for comparison, the accuracy of the results could not be determined. However, due to the scattering of graphs 2 to 7, it was evident that the results had low precision. In the future, repeating the experiment using different and/or new equipment will help detect systematic errors and improve the accuracy and validity of the results.
