The observed osmotic pressure of a solution of benzoic acid in benzene is less than its expected value because
Benzene is a non-polar solvent
Benzoic acid molecules are associated in benzene
Benzoic acid molecules are dissociated in benzene
Benzoic acid is an organic compound
Association of solute takes place
The boiling point of a solution of Benzoic acid in Benzene is less than expected because
