Chapter 7, Problem 7.81E

Interpretation Introduction

Interpretation:

The larger constant between the cryoscopic and ebullioscopic constants is to be identified and the reason for the same is to stated.

Concept introduction:

The $K_{\text{f}}$, the freezing point depression constant, also known as cryoscopic constant is given by the formula given below.

$K_{\text{f}}=\frac{M_{\text{solvent}}R{T}_{\text{MP}}^{\text{2}}}{1000{\Delta }_{\text{fus}}H}$

The $K_{\text{b}}$, the boiling point elevation constant, also known as ebullioscopic constant is given by the formula given below.

$K_{\text{b}}=\frac{M_{\text{solvent}}R{T}_{\text{BP}}^{\text{2}}}{1000{\Delta }_{\text{vap}}H}$
