Question:
The activation energy of a reaction is zero. The rate constant of this reaction
The activation energy of a reaction is zero. The rate constant of this reaction
Show Hint
If activation energy = 0 → rate constant does not depend on temperature.
Updated On: Apr 16, 2026
- increases with an increase of temperature
- decreases with an increase of temperature
- decreases with decrease of temperature
- is independent of temperature
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Arrhenius equation:
\[
k = Ae^{-E_a/RT}
\]
Step 1: Given condition.
\(E_a = 0\)
Step 2: Substitute.
\[ k = Ae^{0} = A \]
Step 3: Conclusion.
Rate constant becomes independent of temperature.
