Being an organic acid, Benzoic acid is a weak acid. Acid means it leaves proton in aqueous solution. The faster the rate of leaving proton, the more strong the acid is. Due to the resonance structure of benzoic acid, power of leaving proton is restricted and that's why its ability to leave proton is restrained.
We know also higher pK
a
value means weaker acid or stronger base.
