1. A Job's Method study was carried out for the reaction
   aA + bB ---> dD + fF

   Stock solutions of A and B containing 1 mmole per 10 mL of solution were prepared. These were used to prepare a series of 8 solutions containing varying amounts of A and B, but such that the total moles of A and B was maintained constant. The absorbance of each solution was then measured at a chosen wavelength (the same for all solutions), and the following data were obtained:

   Solution	volume A solution	volume B solution	A at chosen wavelength
   1	0.3	3.2	0.12
   2	0.4	3.1	0.16
   3	0.5	3.0	0.2
   4	0.7	2.8	0.28
   5	0.9	2.6	0.35
   6	1.2	2.3	0.31
   7	1.5	2.0	0.27
   8	1.8	1.7	0.23

   What is the stoichiometry of the reaction?
