TīmeklisBeer’s law provides a relationship among absorbance, molar absorptivity ( ε), path length (b) and molar concen-tration (c): A = εbc This equation is not Beer’s law; it is the Beer–Lambert law. Beer’s law is A = kc; b is constant; k is a×b, or in the form for molar absorptivity, k is ε×b; a is absorptivity. ruche kenyane avis
