A catalyst:

A. Increases the energy of the activated complex

B. decreases the ∆H of the reaction

C. Decreases the energy of the reactants

D. Decreases the activation energy of the reaction

D

Explanation:

well, just need to remember

Catalyst decreases activation energy

Explanation:

Consider the attached diagram and note the annotation => top of transition diagram for catalyzed reaction is lower than uncatalyzed reaction.

its mg hope this

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
