Concentration of solids in equilibrium

  1. Apr 30, 2014 #1
    It's known that the concentration of solids don't affect the rate of the reaction since it's concentration is constant, I know that when the number of moles of a solid is increased the volume also increases the same so the concentration remains constant so the rate doesn't change, but when the number of moles of a solid increases it's surface area increases which should increase the rate of the reaction. :confused:

    It increases the speed of the reaction, but not the point of the equilibrium, where the reaction happens in the same speed in both directions at the surface.
