APFIVE Beer's Law Data Analysis
The table shows the absorbance of a solution at several concentrations. Which of the following statements best explains how these data support the relationship described by Beer’s law, $$A = abc$$?
| Concentration (M) | Absorbance |
|---|---|
| 0.10 | 0.30 |
| 0.20 | 0.60 |
| 0.30 | 0.90 |
A
The data table shows a linear relationship where doubling the concentration results in a doubling of absorbance, in agreement with the equation $$A = a*b*c$$.
B
The data suggests that absorbance is independent of concentration and is solely determined by the path length of the light through the solution.
C
The table indicates that the relationship between concentration and absorbance is logarithmic, contradicting Beer’s Law.
D
The observed decrease in absorbance with an increase in concentration clearly fails to support Beer’s Law.
