Chapter 11, Problem 11A.3P

Interpretation Introduction

Interpretation:

The molar concentrations of A and B in a cell of length $L$ are $\left[\text{A}\right]=\frac{{\epsilon }_{\text{B2}}{A}_1-{\epsilon }_{\text{B1}}{A}_2}{\left({\epsilon }_{\text{A1}}{\epsilon }_{\text{B2}}-{\epsilon }_{\text{A2}}{\epsilon }_{\text{B1}}\right)L}$ and $\left[\text{B}\right]=\frac{{\epsilon }_{\text{A1}}{A}_1-{\epsilon }_{\text{A2}}{A}_2}{\left({\epsilon }_{\text{A1}}{\epsilon }_{\text{B2}}-{\epsilon }_{\text{A2}}{\epsilon }_{\text{B1}}\right)L}$ have to be shown.

Concept Introduction:

The Beer-lambert law states that the intensity of light absorbed by a solution is directly proportional to the concentration of the solution and the path length of that the light has to travel in the solution.  The mathematical expression for Beer-Lambert law is given below.

    $A=\epsilon cL$
