A murexide soution has a concentration of 3.52x10-4M and an absorbance of 1.850. what is the molar absorptivity of the solution?

The question is incomplete, here is the complete question:

A murexide soution has a concentration of and an absorbance of 1.850 and the path length is 1 cm. What is the molar absorptivity of the solution?

The molar absorptivity coefficient is

Explanation:

To calculate the molar absorptivity coefficient, we use the equation given by Beer-Lambert law, which is:

where,

A = absorbance = 1.850

= molar absorptivity coefficient = ?

C = concentration of the solution =

l = path length = 1 cm

Putting values in above equation, we get:

Hence, the molar absorptivity coefficient is

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
