Question

calculate an approximate heat of reaction, in kilojoules, for the industrial reaction of ethanol with acetic acid to yield ethyl acetate (used as nail-polish remover) and water.

cant figure it out please help!

Explanation / Answer

CH3COOH + C2H5OH ---> CH3COOC2H5 + H2O Lots of the molecules stay exactly the same, so you can eliminate them from consideration. For example, there are a number of C-H bonds, all of which remain undisturbed. These can be eliminated from the calculation. I did not examine it closely,but t it appears that the only bonds broken are a O-H bond in the acetic acid and a C-O bond in the alcohol. Then, for bonds formed, you have a C-O bond in the ethyl acetae and an O-H bond in the water. Approximate heat of reaction is zero.
