If you add a large piece of zinc to a beaker of acid and, in a separate beaker, zinc shavings to a beaker of acid (of equal concentration/volume), the sample with the zinc shavings will react faster than the sample with the large piece. What property causes the difference in rate?

Answer: surface area

Explanation:

Surface area affects rate of reaction. The smaller the surface area the faster the rate of reaction. The zinc shavings have a smaller surface area of reactants compared to the large piece of zinc. The smaller surfaces area of reactants ensures that it comes into close proximity with the acid solution for reaction to take place.
