The same reaction is run with and without a catalyst, with k measured at varied T.
What does the catalyzed line's shallower slope indicate?
- Acheck_circle
A lower activation energy.
- B
A first-order reaction.
- C
A larger frequency factor only.
- D
A higher activation energy.
Explanation
Slope = −Eₐ/R. Shallower (less negative) slope means smaller Eₐ — the catalyst lowers the activation energy.
