which factor causes a decrease in the rate of dissolution?\ndecreasing the amount of solute\nincreasing the stirring of the solution\nincreasing the surface area of the solute\ndecreasing the surface area of the solute\nincreasing the temperature of the solvent

Answer

Brief Explanations:

The rate of dissolution is affected by several factors. Stirring increases the rate as it brings fresh solvent to the solute - solvent interface. Increasing surface area of the solute also speeds up dissolution as more solute is exposed to the solvent. Increasing temperature of the solvent provides more kinetic energy for the dissolution process. Decreasing the amount of solute doesn't directly affect the rate of dissolution but the time to reach saturation. Decreasing the surface area of the solute reduces the contact between solute and solvent, thus decreasing the rate of dissolution.

Answer:

decreasing the surface area of the solute
