Question
Chapter 15, Problem 15.64E
Interpretation Introduction
Interpretation:
The factor that determines the direction in which the reaction, ester hydrolysis, and ester formation proceeds is to be stated. The product formed is to be stated.
Concept introduction:
According to the Le Chȃtelier’s principle, when a change is applied to a reaction, the reaction moves in the direction in such a way to counteract the change. The changes applied may be changed in concentration, pressure, volume, and temperature.

Ester compounds often have a sweet, pleasant odor. Many
characteristic fruit scents are largely due to the natural presence
of one or more ester compounds. As such, artificial scents for
foods are often composed of complex mixtures of various esters.
The exact identity and ratio of ingredients that compose a
particular scent are closely guarded secrets in the food and
fragrance industry.
Suppose that you are a chemist working for a company that i
creating a new line of air fresheners. The company is considering
three scents: apple, pear, and pineapple. The project manager has
asked you to prepare the ester compounds that are largely
responsible for these scents. The structural formulas for these
ester compounds are shown here:

Should they be? b) Compare your average Keq at room temperature to the Keq you measured at elevated temperature. If there is a difference, do you think it is significant, and if so, in which direction has the reaction shifted at the higher temperature? Does this mean the reaction is endothermic or exothermic? c)If the cuvettes are not wiped clean of smudges and fingerprints prior to measuring the absorbances in Part II, will the measured Keq be affected? If affected, will the measured Keq be higher or lower than the true Keq?
