Zora wants to dissolve a solute in a solvent quickly. which best describes what she should do?

a. decrease the pressure

b. decrease the surface area

c. shake it repeatedly

d. place in a refrigerator

Warm up the solvent, crush the solute into powder or small pieces if possible, drop it into the solvent, then agitate the whole thing (shake it or stir it) repeatedly during the dissolving process.  (c)

Decreasing the surface area, or placing it in a refrigerator will both SLOW DOWN the dissolving process.  I don't know what decreasing the pressure will do, but it's not often used as a way to speed up the process.

c.shake it repeatedly

Explanation:

In order to dissolve a solute in a solvent quickly, we need either to increase the temperature or to increase the surface of contact between the solute and the solvent.

Among the options given, we see that

c.shake it repeatedly

can help in make the reaction quicker: in fact, when we shake the compund, more particles of the solute will come in contact with more particles of the solvent. What we are doing, basically, is to increase the surface of contact between the solute and the solvent, so that the reaction will occur quicker.

Choice b) and d), instead, have the opposite effect: they slow down the reaction.
