2. like polarity increases rate rate proportional to K.E.
3. temperature matching solvent and solute
4. stirring finely divided solute

@gators15 I'm trying...

Answer 2

thank you

Answer 3

I think:
1---> "matching solvent and solute", because more solute molecules are able to match molecules solvent:
3--->"concentration decrease around", because statistically speaking molecule speed is proportional to square root of its absolute temperature
4--->"finely divide solute", it is suffice think when we add sugar to coffee and subsequently we perform a stirring of the solution
2-->"rate is proportional to K.E."

Answer 4

for last matching, namely 2--->"rate is proportional to K.E.", a simple explanation may be this:
when a solvent molecule polarity is increase, that molecule is able to perform bond with solute molecules, more easily, even if that solvent molecule can bond only molecules solute that are very close to such molecule solvent, so in order to that molecule solute have to have more kinetic energy.
