Question

Beer Lambert’s law indicates _______.

• A. absorbance is directly proportional to concentration
• B. absorbance is indirectly proportional to concentration
• C. absorbance is indirectly proportional to path length
• D. absorbance is indirectly proportional to molar absorptivity

Hint:

Absorbance increases linearly with concentration under Beer Lambert’s law.

Answer 1

The Correct Option is A

Beer Lambert's law states that absorbance (A) is directly proportional to the concentration (c) of the absorbing species and the path length (l), expressed as \( A = \varepsilon cl \), where \( \varepsilon \) is the molar absorptivity.
