Answer:

Option C, an increase of reaction rate with increase in temperature

Explanation:

Colligative properties are as follows

a) Decrease of vapor pressure

b) Increase of boiling point

c) Reduction of freezing point

d) Increase of osmotic pressure

There is no impact on reaction rate and hence it is not a colligative property.

Thus, option c is the right choice

An increase of reaction rate with increase in temperature isn't an example

of colligative properties of solutions

Colligative properties of solutions depend on the ratio of the number of

solutes to that of the solvent(concentration) and not on the nature of the

substances involved.

Examples of colligative properties include vapor pressure lowering, boiling

point elevation, freezing point depression, and osmotic pressure. Increase of

reaction rate with increase in temperature is therefore not an example of

colligative properties of solutions.
