Question

which factor influences both solubility and the rate of dissolution?
pressure
temperature
particle size
nature of solvent

Explanation:

• Pressure mainly affects the solubility of gases.
• Temperature impacts both solubility (e.g., for most solids in liquids, solubility increases with temperature; for gases in liquids, it decreases) and the rate of dissolution as higher - temperature particles have more kinetic energy to dissolve faster.
• Particle size affects the rate of dissolution (smaller particles dissolve faster) but not solubility.
• The nature of the solvent affects solubility (like dissolves like principle) but not as directly the rate of dissolution as temperature.

Answer:

B. temperature
