Question 23
H

Ethyl ethanoate is made by the reversible reaction shown. As the reaction takes place, the water is removed from the mixture.

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

What is the effect on the yield of ethyl ethanoate?

[1]
A

The yield falls, because a product has been taken away

B

The yield falls, because the reverse reaction becomes faster

C

The yield rises, because more reactants react to replace the water

D

The yield rises, because the forward reaction becomes exothermic
