For the depression in freezing point experiment, the correct statement(s) is/are: 

According to Raoult's Law:

At a given temperature, the partial pressure of each component is equal to the product of vapor pressure of the pure component and its mole fraction (x).

$\mathrm{p}={\mathrm{xp}}^{\circ }$

If a solution starts to freeze, the solvent molecules will solidify, leaving the non volatile to form a more concentrated  solution.
