APCHEM-BI8WYT

Study the potential energy diagram of a chemical reaction below:

"Chemical Kinetics." Wikipedia. Wikimedia Foundation, 5 Mar. 2016. Web. 20 Mar. 2016.

The red dotted line represents the new reaction pathway created by the addition of a catalyst.

Which of the following describes how the new reaction pathway works to speed up the reaction?

A

The presence of the catalyst provides two different pathways for the reactants to form products.

B

The catalyst lowers the activation energy required by the reaction, leading to a more stabilized transition state.

C

The catalyst lowers the heat of reaction, leading to a less stabilized transition state.

D

The catalyst alters the reactants, leading to an alternate energy pathway.
