also necessitates a conservation of "mass" indicating, for a constant sample size, an isosbestic point in the data curves.3. If the points lie in a straight line, one can determine a reaction rate constant, k, for A = B from the spacing of the points.4. If the points fall on a line through the origin, the proportion of A and B is constant and the sample size is changing. The distance from the origin along this line is proportional to the sample size. 5. If one uses a constant sample size and runs an unknown mixture and successive dilutions of this mixture with one component, the composition of the unknown mixture can be determined from its distance from the boundaries along a line parallel to 9. Figure 10 is an example for a 50:50 "unknown" mixture of A and B. Three other samples are prepared by sequential dilutions (1:1) withIf the sample size is not constant, the points will not be in a line, but the analysis can still be obtained by passing line 9 through each original sample point and measuring as above.
ACKNOWLEDGMENTThe discussions with William Lawton and the help of Paul Taylor with some of the experimental work and with the final drawings are greatly appreciated.
