Given that △ Tf if is the diperssion in freezing point of the solve

Question

Given that

△ T_{f}

if is the diperssion in freezing point of the solvent of non-volatile solute of molality m, the quantity

l i m m \to 0 (\frac{△ T_{f}}{m}) i s e q u a l t o

Options:

A . Zero

B . One

C . ∞

D . Finite value

Answer: Option D
:
D

△ T_{f} = K_{f} m

l i m m \to 0 (\frac{△ T_{f}}{m}) = l i m m \to 0 (K_{f}) = K_{f}
