Question

Which would increase the rate of dissolving? Check all that apply.

low temperature
little to no agitation
more surface area
high temperature
a lot of agitation
little surface area

Answer 1

Step-by-step explanation:

Rate of dissolution means the rate at which solute is able to dissolve in the solvent.

Dissolution of solute depends on temperature, agitation, and surface area.

More is the temperature provided more is the solute able to dissolve into the solvent.

More is the surface are more will be number of molecules of solute in contact with the molecules of solvent. Therefore, rate of dissolution will increase with increase in surface area.

Agitation means to stir quickly, this will increase the number of collisions between solute and solvent particles. Therefore, rate of dissolution will increase with increase in agitation.

Thus, we can conclude that factors that would increase the rate of dissolving are as follows.

• more surface area.

• high temperature.

• a lot of agitation.

Answer 2

Answer: The factors that increase the rate of dissolving are

1) More surface area

2) High temperature

3) A lot of agitation

Explanation: Rate of dissolving is defined as the measure of how fast the solute gets dissolved in a solvent. This rate is affected by 3 factors:

1) Surface area: There is a direct relation between the surface area and the rate of dissolving.

`\text{Surface area}\propto \text{Rate of dissolving}`

More the surface area, higher is the rate of dissolving.

2) Temperature: This also have a direct relation with the rate of dissolving.

`Temperature\propto \text{Rate of dissolving}`

More is the temperature, more will be the rate of dissolving.

3) Amount of agitation: There is also a direct relation between amount of agitation and rate of dissolving.

`\text{Amount of agitation}\propto \text{Rate of dissolving}`

A lot of agitation will result in the higher rate of dissolving.
