QUESTION 2 How do we obtain kX? ODividing the Absorbance by the concentration, it is the quotient. Dividing the Absorbance by the wavelength, it is the quotient O Plotting absorbance vs concentration, it is the slope Plotting absorbance versus volume, it is the slope None of the above QUESTION 3 In Lambert-Beer equation, A-kA-c OA is in nanometers, kA is in M-1 and c is in moles/liter. 0 A has no units, k? ?s in M-1 and c is in moles/liter. 0 A is in Molar, k? has no units in Molar. Using units is never recommended. None of the above QUESTION 4 In a diluted solution water is added and the concentration increases water is added and the volume decreases water is added and the concentration decreases. water is added and the number of moles decreases. None of the aboveExplanation / Answer
Question 2
It can be obtained by dividing the absorbence by concentration . It is the quotient . It is beer lamberts law . Hence correct option is first option .
Question 3
Absorbence itself has no units . Hence correct option is second one .
Question 3
In any solution when we add water to it the concentration os solute decreases . So correct option is third one .
