Factors that affect the rate of reactions
... Surface area is a measure of how much area is exposed. If the surface area is large, then there is a better chance of hitting another reactant so the reaction rate will be high. The greater the surface area the higher the reaction rate. Surface area ONLY affect reactants that are in DIFFERENT phases ...
