Preezing Point Depression In addition to raising the boiling point, the dilution of a liquid will diminish the freezing point and for reasons that are exactly analogous to the boiling point elevation. Using the Clausius-Clapeyron equation, one may solve for the freezing point of a solution as: which, of course, you’ll recognize as looking a whole lot like Equation 4, except that it involves the heat of fusion of A and the freezing point of pure A, TP. Again, the change in freezing point may be calculated making analogous approximations as the boiling point elevation in order to obtain: where Kr is the molal freezing point constant whose value, again, depends on the solvent. Critical Thinking Questions Given that the heat of fusion of water is 6.01 kJ/mol, calculate the freezing temperature of a 25% ( solution of antifreeze (ethylene glycol, M IC 3. 62.07 gmol in water te the molal freezing point com
