“…Equation 3 stipulates that a plot of 1 /[M]0t vs. [A]e/[M\0, the mole fraction of A, at a given fraction of reagent reacted, [R]t/{R]0, yields a straight line which can serve as a calibration curve for the determination of binary mixtures. Reilley (6) pointed out that the most reliable measurements are made when the fraction [R]t/[R\0 is chosen to be 1/e. Thus, in Figure 1, Bo/(Ao + Bo 5 In a case where both of the components are available in pure form, the calibration curve can simply be determined by application of the abovementioned operations for single compound A to yield the value l/(íe [A ]") and for B to yield \/{te[B]"), and by connecting these two data points by means of a straight line.…”
