Why does changing the temperature affect the rate of dissolving?
Changing the temperature changes the average kinetic energy of the solution's particles. This changes their speed, leading to more or fewer solvent-solute interactions.
Changing the temperature changes the color of the solution's particles. This makes them more interesting to each other and draws them together.
Changing the temperature changes the number of moles of particles. More moles of particles dissolve faster.
Why does agitating the solution affect the rate of dissolving?
Agitation moves the particles around more, leading to more solvent-solute attractions.
Agitation forces the solvent particles into a crystalline conformation.
Agitation leads to increased colligative properties, which speeds dissolving.
Why does changing the solute surface area affect the rate of dissolving?
Changing the surface area changes how quickly the solvent particles can access the solute particles, which changes the speed of solute-solvent attractions forming.
Changing the surface area changes how light refracts on the solute, heating it up and speeding the dissolution.
Changing the surface area makes more space for new solute to be added, making it dissolve faster.
