August 2019 NY Regents Chemistry Exam
41 Hydrochloric acid reacts faster with powdered zinc than with an equal mass of zinc strips because the greater surface area of the powdered zinc
(1) decreases the frequency of particle collisions
(2) decreases the activation energy of the reaction
(3) increases the frequency of particle collisions
(4) increases the activation energy of the reaction
Solution: The higher the frequency of particle collisions, the higher the rate of the reaction.
