Answer:

the decrease in the freezing point of a solution as a function of the number of particles that are dissolved in the solution

Explanation:

Depression of freezing point is given by the equation:

ΔTf = m. Kf. i

where i is the Van't Hoff factor or the number of particles of solute, m is the molality, and Kf is the freezing point depression constant.

As per the formula, depression of freezing point is directly proportional to the

Van't Hoff factor or the number of particles of solute.
