Problem 1SE

The Beer-Lambert law relates the absorbance A of a solution to the concentration C of a species in solution by A = MLC, where L is the path length and M is the molar absorption coefficient. Assume that L = 1 cm. Measurements of A are made at various concentrations. The data are presented in the following table.

Concentration (mol/cm3)

1.00

1.20

1.50

1.70

2.00

Absorbance (L/cm3)

0.99

1.13

1.52

1.73

1.96

a. Let  be the equation of the least-squares line for predicting absorbance (A) from concentration (C). Compute the values of and .

b. What value does the Beer-Lambert law assign to β0?

c. What physical quantity does  estimate?

d. Test the hypothesis H0: β0 = 0. Is the result consistent with the Beer-Lambert law?
