* Surface Area: Crystals have a much larger surface area compared to a single sugar cube of equal mass. This is because the crystals are smaller and have more exposed surfaces.
* Reaction Rate: Chemical reactions occur at the interface between reactants. A larger surface area means more points of contact for the reactants, leading to a faster reaction rate.
Think of it like this: Imagine you're trying to dissolve sugar in water. The smaller crystals would dissolve much faster than a large cube because they have more surface area exposed to the water. The same principle applies to chemical reactions.
