Statement $I$ is correct,but statement $II$ is not correct

Vedclass · Answer

(B) Statement-$I$: The elevation in boiling point $\Delta T_b$ is given by $\Delta T_b = i 	imes K_b 	imes m$.For $0.1 \ M$ urea (non-electrolyte),the van't Hoff factor $i = 1$.For $0.1 \ M$ $KCl$ (electrolyte),$KCl$ dissociates as $K^+ + Cl^-$,so $i = 2$.Since $\Delta T_b \propto i$,the boiling point of $KCl$ solution is higher than that of urea solution. Thus,Statement-$I$ is correct.Statement-$II$: Elevation of boiling point is a colligative property,which depends on the number of solute particles,not on the molar mass of the solute. Thus,Statement-$II$ is incorrect.

Observe the following statements:
Statement-$I$: The boiling point of $0.1 \ M$ urea solution is less than that of $0.1 \ M$ $KCl$ solution.
Statement-$II$: Elevation of boiling point is inversely proportional to molar mass of solute.
The correct answer is:
