A factor that decreases the activation energy for a reaction:
I.decreases the rate constant
II.increases the rate constant
III.has no effect on the rate constant
IV.increases the product yield
V.might be a catalyst

Question

Quizplus · Accepted Answer

A factor that decreases the activation energy for a reaction increases the rate constant, which is option II. This factor might be a catalyst, which is option V. However, it does not affect the product yield or have no effect on the rate constant, eliminating options I, III, and IV. Therefore, the best choice is E - II and V.
