According to Beer's law a. the absorbance is proportional to the reciprocal of the concentration. b. the absorbance is proportional to the concentration. c. the absorbance is proportional to the square of the concentration.

b. the absorbance is proportional to the concentration.

Explanation:

Beer's law states that the amount of energy absorbed or transmitted by a solution is proportional to the solution's molar absorptivity and the concentration of solute.

This means that concentrated solution absorbs more light than dilute solutions.

Going trough the options;

The correct option is option B. This is because as the concentration increases, the absorbance also increases. Hence absorbance is directly proportional to the concentration.

girl imma just put my comment here because i need a couple point okurrttt
