2. Beaker A contains a 1-grams piece of zinc and beaker B contains 1 gram of powdered zinc. If 100 milliliters of 0.1 M HCl is added to each of the beakers, how does the rate of reaction in beaker A compare to the rate of reaction in beaker B?
a) The rate in A is greater due to the smaller surface area of the zinc.
b) The rate is A is greater due to the greater surface area of the zinc.
c) The rate in B is greater due to the smaller surface area of the zinc.
d) The rate is B is greater due to the greater surface area of the zinc.
