Question

21.Which of the following is the best explanation for the fact that crushing increases the rate at which a solid dissolves in a liquid?Select one:a. The temperature of the solution is increased when the solid is crushed.b. The surface area of the solute is increased when it is crushed.c. Crushing increases the amount of solute present.d. Crushing makes stirring the solution easier.

Answer 1

A few factors help a solution to have its rate increased, and one of these factors is surface area, when the surface area is increased, more of the solute is in direct contact with the solution, making the reaction to occur faster, therefore when you crush the solute into smaller pieces, the reaction rate will be increased, letter B
