Question 19

Ethanoic acid and ethanol form a liquid equilibrium mixture in a closed container.

ethanoic acid + ethanol ⇌ \rightleftharpoons\,⇌ ethyl ethanoate + water

The forward reaction is exothermic. After each change, the mixture is allowed to reach a new equilibrium.

Statement 1: Adding water increases the amount of ethanoic acid in the equilibrium mixture.

Statement 2: Cooling the mixture increases the amount of ethyl ethanoate in the equilibrium mixture.

Statement 3: Removing some ethanol increases the amount of ethyl ethanoate in the equilibrium mixture.

Which statements are correct?
