An expansion of reaction rate with growth in temperature isn't an instance of colligative properties of solutions.
The four colligative properties that can be displayed by a solution exist:
There exist four colligative properties: vapor pressure decreasing, boiling point elevation, freezing point depression, and osmotic pressure. This indicates that a solution indicates a reduced vapor pressure, an advanced boiling point, and a reduced freezing point in comparison to the pure solvent.
Colligative properties of solutions related on the ratio of the number of
solutes to that of the solvent(concentration) and not on the behavior of the substances concerned.
