Question

Molar extinction coefficient from Beer's Law plot (word doc):

a) Varies with concentration
b) A constant
c) Dependent on temperature
d) None of the above

Answer 1

The molar extinction coefficient from Beer's Law plot is a constant.

Step-by-step explanation:

The molar extinction coefficient from Beer's Law plot is a constant (option b).

The molar extinction coefficient, also known as molar absorptivity (ɛ), is a characteristic value for a given compound.

It represents the relationship between the concentration of a sample and the absorbance (A) of light passing through the sample.

It is constant for a specific compound and is used to determine the concentration of the compound in a solution.
