Question

Why does reducing solute particle size increase the speed at which the solute dissolves in water? A. It exposes more of the solute to the water molecules. B. It makes the temperature of the water significantly higher. C. It raises the pressure of the water molecules on the solute. D. It makes the water molecules move around faster.

Answer 1

Answer:A

Explanation:For a given amount of solute, smaller particles have greater surface area. With greater surface area, there can be more contact between particles of solute and solvent.
