Answer 1

@vera_ewing I know the answer!

Answer 2

Well, I know that catalysts decrease the activiation energy, and in turn speed up the rate of a chemical reaction if that helps (I got a 5 on bio this year)

Answer 3

Hm, okay. So which one should I choose?

Answer 4

Hold on, I'm thinking :)

Answer 5

I'd say either A or D.

Answer 6

so I'm just going with A. But you should get further proof. I would ask in the biology section instead of math:)
