Answer:
is the concentration of the compound in a solution.
Explanation:
Using Beer-Lambert's law :
Formula used :

Where:
A = absorbance of solution
C = concentration of solution
l = path length
= molar absorptivity coefficient
We have:
C = ? , l = 1.00 cm, A = 0.090



is the concentration of the compound in a solution.
Endo is more in reactants and exo is more in products because in exothermic reactions heat is released
