A chemical reaction will proceed more rapidly if there is a decrease in
Show Hint
A lower activation energy makes the exponential term larger.

- \(k\)
- \(A\)
- \(E_a\)
- \(T\)
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Think in terms of barrier
A smaller energy barrier lets more molecules cross it at a given temperature.
Step 2: Link to formula
Smaller $E_a$ raises $e^{-E_a/RT}$, raising $k$. The other choices lower or do not raise $k$. Option (C).
Final Answer:
Lower Ea. \[ \boxed{\text{(C)}\ E_a} \]
