Answer:

I > III > II

Explanation:

The osmotic pressure (π) is a colligative property that can be calculated using the following expression.

π = M × R × T

where,

M is the molarity of the solution

R is the ideal gas constant

T is the absolute temperature

As we can see, there is a direct proportionality between the molarity of the solution and its osmotic pressure. As a consequence, the correct order for osmotic pressures is:

I > III > II

The order of increasing osmotic pressure for the nonvolatile solutions is I> III > II.

Osmotic pressure is a colligative property. The osmotic pressure of a solution refers to a pressure applied to avoid net movement of water across a semi permeable membrane. Osmotic pressure is obtained from the relation;

π = M × R × T

Since osmotic pressure depends on the molar concentration of the solution, the order of increasing osmotic pressure for the nonvolatile solutions is I> III > II.
