MCQ
What does the Beer-Lambert Law (A = epsilon x l x c) relate?
Chemistry
A Temperature and pressure of a gas
B Absorbance to concentration, path length, and molar absorptivity
C Rate of reaction to concentration
D Voltage to current and resistance
Explanation

Beer-Lambert Law states absorbance (A) = molar absorptivity (epsilon) x path length (l) x concentration (c), forming the basis of quantitative UV-Vis analysis.
