Question

1. which property listed below does not apply to a catalyst?

a. lowers the overall activation energy of a reaction
b. increases the number of collisions
c. reacts in one step but is regenerated in another step
d. provides an alternate path for the reaction
e. breaks a single step reaction into more, lower energy
steps

Explanation:

To determine which property does not apply to a catalyst, we analyze each option:

• Option a: Catalysts lower the activation energy of a reaction, so this applies.
• Option b: Catalysts increase the rate of reaction by providing an alternate path, which can be related to effective collisions, so this applies.
• Option c: Catalysts are consumed in one step and regenerated in another (they are not used up overall), so this applies.
• Option d: Catalysts provide an alternate reaction pathway, so this applies.
• Option e: A catalyst does not convert a single - step reaction into multiple steps. A single - step reaction remains a single - step reaction; catalysts provide an alternate path for the reaction (which may have different steps than the uncatalyzed reaction, but they don't break a single - step reaction into multiple steps).

Answer:

e. Converts a single step reaction into more, lower energy steps
