(a) Use linear regression and the Benesi-Hildebrand equation
(Equation 14-11) to determine the formation constant and the difference in
molar absorptivities at 470 nm.

(b) Use nonlinear regression and Equation 14-10 to find the
values of Kf  and Δe. Start with initial estimates of Kf
= 50 and De = 50.
