Derive the Scatchard equation for a reaction system 2P + X ↔ P2X, in which only P and P2X have measurable absorbances at the chosen wavelength. Based on this equation and the data given below, determine the values of Keq and ??2? (epsilon P2X). Assume the width of the cuvet used in all of these measurements to be 1cm, i.e., b = 1cm,and the absorbance of the blank solution to be zero.
