Tardigrade Admin · Accepted Answer

When benzoic acid dissolve in benzene it will be dimerize due to the intermolecular hydrogen bonding

2 C_{6} H_{5} COO H benzene (C_{6} H_{5} COO H)_{2}

= \frac{No. of particles after association or dissociation}{No. of particles before association or dissociation}

= \frac{1}{2} = 0.5
