JEE Main 4 April 2025, Shift 2, Chemistry Q53

Question 53 of 75 in this shift, Chemistry question 3 of 25, Section A.

Given below are two statements : Statement (I) : Molal depression constant KfK_f is given by M1RTfΔSfus\frac{M_1RT_f}{\Delta S_{fus}}, where symbols have their usual meaning. Statement (II) : KfK_f for benzene is less than the KfK_f for water. In the light of the above statements, choose the most appropriate answer from the options given below :
  1. (1)Both Statement I and Statement II are correct
  2. (2)Both Statement I and Statement II are incorrect
  3. (3)Statement I is correct but Statement II is incorrectOfficial answer
