Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

acetate ion is more acidic due to two equivalent resonating structure by which the stability is more than phenoxide ion. while in case of phenoxide ion there is no such equivalent resonance

Acetate ion is more stable than phenoxide ion due to two equivalent resonating structures in acetate ion. Phenoxide ion has non-equivalent resonance structures in which the negative charge is less effectively delocalised over less electronegative carbon atom and one oxygen atom. The carboxylate ion is more stable than the phenoxide ion. This is because in the phenoxide ion, the negative charge resides on one electronegative oxygen atom and the lesser electronegative carbon atoms. Consequently their contribution towards resonance stabilisation of the phenoxide ion is less.
