Which statements about the Arrhenius equation are correct?
Hints
- Read where each symbol sits in the exponent before judging its effect.
- A larger activation energy makes the exponential term smaller.
Show the answer
- A. A catalyst increases k by lowering
- C. k increases as temperature T increases
- D. k is independent of reactant concentration
Why
A higher slows the reaction (fewer molecules have enough energy), not speeds it up.
