Question

classify each action as something that speeds up the rate at which solutes will dissolve or slows down the rate at which solutes will dissolve in a solution. speeds up rate: stirring, heating, use smaller solute particles, crushing solute. slows down rate: cooling, use larger solute particles

Explanation:

Step1: Analyze stirring

Stirring increases the contact between solute and solvent, speeding up dissolution.

Step2: Analyze heating

Heating provides more kinetic energy, increasing the rate of dissolution.

Step3: Analyze using smaller solute particles

Smaller particles have a larger surface - area to volume ratio, allowing for faster dissolution.

Step4: Analyze crushing solute

Crushing solute is similar to using smaller particles, increasing surface area and speeding up dissolution.

Step5: Analyze cooling

Cooling reduces the kinetic energy of particles, slowing down dissolution.

Step6: Analyze using larger solute particles

Larger particles have a smaller surface - area to volume ratio, resulting in slower dissolution.

Answer:

Speeds up rate: stirring, heating, use smaller solute particles, crushing solute
Slows down rate: cooling, use larger solute particles
