Answer:
For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.

Answer: Rate of reaction is an "extensive property". Rate of generation of a chemical species is an "intensive property"
Explanation:
- Let´s check out the Factors that affect the speed of reactions:
Temperature, Physical state of the reagents, Presence of a catalyst, Pressure, light, Concentration of the reagents.
When having a general chemical reaction like this:
aA + bB → cC + dD
Usually the rate of reaction is represented by the next equation
![Rate = k [A]^{x} [B]^{y}](https://tex.z-dn.net/?f=Rate%20%3D%20k%20%5BA%5D%5E%7Bx%7D%20%5BB%5D%5E%7By%7D)
Where k= constant
x, y = reactant orders
A, B = reactant concentration
As we can see in the last equation, the rate of reaction <u>depends directly of the amount of material present</u> in a sample, that is why it is an "extensive property"
- The rate of generation of a chemical species, depends of other factors like Temperature, Presence of a catalyst, Pressure. As we can see all the factors that allow the speed of generation of a new chemical species let us know that this is an<u> </u><u>intensive property</u><u> because it doesn´t depends of the amount of material.</u>
3, 9, 16 are correct! 17 should be b because buffered means that it resists change in pH
