Answer :
Part A Part B
1) increased surface area → C) finely divided solute
2) like polarity increases rate → D)matching solvent and solute
3) temperature → A)rate proportional to K.E
4) stirring → B)concentration decreases around solute
Explanation :
1) Greater the surface area, the faster the substance will dissolve. When we are finely divided the solute then the surface area increased.
2) A polar molecule will dissolve in other polar molecules, but it will not dissolve in non-polar molecules.
3) Temperature is directly proportional to the kinetic energy. As the temperature increases, the kinetic energy also increases.
4) Stirring a solute into a solvent, the dissolving rate increases and the concentration decreases around the solute.
