Ortho substituents complicate due to steric influence as well. Meta substituents are not in through resonance with the carbonyl group of benzoic acid. Electron withdrawing group increases dissociation while electron donating decrease dissociation of benzoic acid. The influence is studied at a specific temperature 25 0 C and a specific solvent like water. Thus the relation can be expressed as. The relation between free energy and equilibrium constant is.
