Question

1. which of the following statements is true about catalysts? a. catalysts provide an alternative reaction pathway with lower activation energy. b. catalysts slow down the reaction rate. c. catalysts increase the activation energy needed for a reaction. d. catalysts are consumed in the reaction.

Explanation:

Catalysts work by providing an alternative reaction pathway with a lower activation energy, which speeds up the reaction rate. They are not consumed in the reaction and do not increase the activation energy.

Answer:

A. Catalysts provide an alternative reaction pathway with lower activation energy.
