Answer 1

Please do not comment unless you are making a serious attempt at a solution.

Answer 2

I thought way too long on this. Does this resonance structure make the H a better leaving group?

That would make acetic acid stronger and the resulting species, acetate ion, would be more stable, which also contributes to the fact that this resonance structure is more stable
