On addition of naphthalene to benzene, there is a depression in the freezing point of benzene. This is due to the presence of a non-volatile solute (naphthalene), which lowers the freezing point.
Given below are two statements:
Statement (I): Molal depression constant $ k_f $ is given by $ \frac{M_1 R T_f}{\Delta S_{\text{fus}}} $, where symbols have their usual meaning.
Statement (II): $ k_f $ for benzene is less than the $ k_f $ for water.
In light of the above statements, choose the most appropriate answer from the options given below:
Match List-I with List-II: List-I
