Which side will the equilibrium of the following acid/base reaction lie and why?

Question

Quizplus · Accepted Answer

The equilibrium of this acid/base reaction will lie to the right because ethoxide is a stronger base than acetate. This is because the negative charge on the oxygen atom in ethoxide is more stabilized by the carbon atom in the ethoxide molecule than in the acetate molecule. Therefore, ethoxide is more likely to accept a proton from the acid, which will drive the equilibrium to the right.
