Rate of Dissolving
Does the rate of dissolving always increase with increasing temperature, or are there a few cases where it does not?
Re: Rate of Dissolving
Hi smcgonigle17,
The “rate of dissolving” refers to how quickly a solute will dissolve in a solvent. Heating the solvent increases the kinetic energy, causing more frequent collisions of solvent and solute molecules. More frequent and forceful collisions increase the rate of solute dissolving. This behavior is expected for solid solutes and liquid solvents.
More details about dissolving rate and solubility can be found here:

I hope this helps. Please post again if you have more questions.
