Reactions between alcohol and carboxylic acid produce esters. However, these reactions do not go to completion, and instead, reach an equilibrium. The most commonly produced ester is ethyl acetate (CH3COOCH2CH3), which is used as a solvent in the pharmaceutical industry and to decaffeinate coffee and tea. Ethyl acetate is produced by reacting ethanol (the alcohol that gets you drunk) with acetate (the acid in vinegar), show in the reaction below:
CH3CH2OH(l) + CH2COOH(l) <-> CH3COOCH2CH3(l) + H2O(l) Kc = 3.96 at 80 degree C
At 80 C, 100 g of ethanol, 1oo g of acetic acid, 100 grams of ethyl acetate, and 100 g of water are added ti a 3.333 L vessel.
What is Qc for the reaction? Answer to three significant figures.
Will the reaction move to the left or to the right as it moves to equilibrium. Answer "left" or "right".
