As temperature rises, the kinetic energy of particles increases and this increases their chance of collision to form a stable compound. If the temperature increases, will some particles combine less than past as they fail to attract the other due to their high speeds?

For a chemical reaction to occur first activation energy must be past, by raising the temperature more particals will achieve activation energy and thus create more products. You are correct in both your assumptions heres an example HCl(aq) + Fe if you were to heat this up the reaction would take place faster as you suggested (particle movement). But once you raise the temperature beyond a certain point the product will decompose so the reaction won't take place because the system is too energetic to supoort the products. So in a practical sense heating up system will increase the rate of reaction due to both activation energy and particle movement, but once you get past a certain point the energy will be too great to support the reaction.

Not as far as I know, because it is collisions not attractions.

Activation Energies: Heat (collisions), Surface Area, Catalysts.

 

if my memory serves me correctly, those are the 3 main factors in Reaction Speed.

Thank you.
