0.01 m AgNO_{3} < 0.03 m CuSO_{4}< 0.04 m urea

As molal concentration rises, so does freezing point depression. It can be expressed mathematically as ΔTf = Kfm.

<h3>What is Colligative Properties ?</h3>
  • The concentration of solute particles in a solution, not the composition of the solute, determines a colligative properties .
  • Osmotic pressure, boiling point elevation, freezing point depression, and vapor pressure reduction are examples of ligand-like properties.
<h3>What is freezing point depression?</h3>
  • When less of another non-volatile material is added, the temperature at which a substance freezes decreases, a process known as Freezing-point depression.
  • Examples include combining two solids together, such as contaminants in a finely powdered medicine, salt in water, alcohol in water.
  • An significant factor in workplace safety is freezing points.
  • If a substance is kept below its freezing point, it may become more or less dangerous.
  • The freezing point additionally offers a crucial safety standard for evaluating the impacts of worker exposure to cold conditions.

klemol [59]

Answer : The correct option for blank 1 is, Forward and Backward direction .

The correct option for blank 2 is, Reach equilibrium .

Explanation :

  • Reversible reaction : It is a reaction in which two or more reactants react together to give products and these products react with other product to form reactants.

It occurs in both the directions at the same time, forward and backward direction.

  • Irreversible reaction : It is a reaction in which reactants react together to give a product but it can not revert back into the reactants.

It occurs in forward direction only.

  • Equilibrium reaction : It is a reaction in which the rate of forward reaction is equal to the rate of backward reaction.
  • Completion reaction : It is a reaction in which the reactants react together to give products. when the reaction goes to completion theta means all the reactants are used up and you have only products in the reaction.
