why does grinding a solid into a powder increase reaction rate

  • Factors Affecting Reaction Rates

    Factors Affecting Reaction Rates

    The surface area is the sum of the area of all six sides of the cube. The surface area of the cube can be increased by dividing the cube into smaller cubes. Surface area is maximized when a single large cube is crushed to fine powder. The rate of reaction of a solid substance is related to its surface area.

  • Why Does an Increase in Reaction Temperature Generally

    Why Does an Increase in Reaction Temperature Generally

    Why Does an Increase in Reaction Temperature Generally Increase the Reaction Rate Temperature increases the reaction rate by increasing the number of collisions and making more forceful collisions. A rise in temperature is an increase of motion and energy so collisions happen more often and more violently resulting in product formation.

    The Effect of Surface Area

    As we increase the surface area of the reactants we increase the rate of reaction. Increasing the surface area of a solid reactant exposes more of its particles to attack. This results in an increased chance of collisions between reactant particles so there are more collisions in any given time and the rate of reaction increases.
