Based on Beer\'s law, the absorbance of standard dye solutions at Amax (A) shoul

Question

Based on Beer's law, the absorbance of standard dye solutions at Amax (A) should be linearly dependent on the corresponding dye concentrations (C). In other words, if a calibration curve (standard curve) is made by plotting the absorbance of standard dye solutions at Amax against the corresponding dye concentrations, the calibration curve should be a linear line, and the slope of the calibration curve is El. In accordance with Beer's Law, the slope of the linear trendline on a plot of absorbance versus concentration is equal to___-- the equilibrium constant the light path length the transmittance C the product of the molar extinction coefficient and the path length C the molar extinction coefficient

Explanation / Answer

as per Beer's law, A(absorbance)= e(moalr extinction coefficient)*b*(path length)*C(concentration)

so a plot of A vs C gives straight line whose slope is product of molar extinction coefficient* path length. 4 is correct.
