plz tell d definition of molal depression constant & molecular depression constant i know d formula plz tell d definition constant

dream_iit

it is defined as the depression in freezing point when the molality of the solution is unity
unit - Kelvin Kg/mol

molal depression constant----->Freezing-point depression decribes the phenomenon that the freezing point of a liquid (a solvent) is depressed when another compound is added, meaning that a solution has a lower freezing point than a pure solvent. This happens whenever a solute is added to a pure solvent, such as water. The phenomenon may be observed in sea water, which due to its salt content remains liquid at temperatures below 0°C, the freezing point of pure water.
molecular depression constant---->its the Molecular Weight by Freezing Point Depression . When one mole of a nonvolatile, nondissociating (nonelectrolyte) solute is dissolved in 1.000 kilograms of solvent, the freezing point of the solvent is lowered by some constant amount...rate f satisfy...thanks
