(Q72) Why does the experimentally observed van't Hoff factor frequently differ from the predicted value? O Varying degrees of residual ionic attractions prohibit the ions as acting as totally independent particles Compounds that completely dissociate have a van't Hoff factor twice of that predicted O A complete lack of particle interaction results in a lowered experimental value O A complete lack of particle interaction results in an increased experimental value Interference from nonelectrolytes lowers the experimental value
