In case of association, abnormal molar mass of solute will:
Step 1: Understanding association. In case of association, solute molecules aggregate, resulting in a reduction in the number of particles in the solution. This causes the molar mass to appear lower than the expected value.
Step 2: Conclusion. Thus, the abnormal molar mass decreases in case of association, corresponding to option (B). \vspace{10pt}
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:
