Regents Chemistry Exam June 2025 Question 38
39 Which statement explains why a catalyzed reaction occurs at a faster rate than the same reaction when uncatalyzed?
(1) The catalyst provides a different reaction pathway for the reaction with a lower activation energy.
(2) The catalyst provides a different reaction pathway for the reaction with a higher activation energy.
(3) The catalyst uses the same reaction pathway for the reaction with a lower activation energy.
(4) The catalyst uses the same reaction pathway for the reaction with a higher activation
energy.
Solution:
A catalyst speeds up a reaction by providing an alteranate reaction pathway and lowering activation energy. Therefore, a catalyzed reaction occurs at a faster rate because it uses a different reaction pathway that has a lower activation energy. Choice 1 is the correct answer.
