Ethyl acetate, a solvent used in many fingernail-polish removers, is made by the reaction of acetic acid with ethanol: C H 3 C O 2 H ( s o ln ) + C H 3 C H 2 O H ( s o ln ) ⇌ C H 3 C O 2 C H 2 C H 3 ( S o ln ) + H 2 O ( s o ln ) Δ H ° = − 2.9 k j Does the amount of ethyl acetate in an equilibrium mixture increase or decrease when the temperature is increased how does K change when the temperature is decreased? Justify your answers using Le Chatelier’s principle.

Justify your answers using Le Chatelier’s principle.
Solution Summary: The author explains Le Chatelier's principle that if a change occurs in terms of concentration, pressure, temperature or volume in an equilibrium system, the net reaction occurs to counteract the change.
