Compound P binds with X to form the complex PX. A series of solutions was prepared with the total P concentration remaining fixed at 1.00 x10-5M in all solutions. Both P and X do not absorb at 437 nm, but PX has an absorption maximum at 437 nm. The following table shows how the absorbance at 437 nm in a 5.00 cm cell depends of [X], using the assumption that [X]is approximately qual to XTbecause XT>>*P+.
