Question:
Which one of the following does not represent the Arrhenius equation?
Which one of the following does not represent the Arrhenius equation?
Show Hint
The Arrhenius equation shows that higher Ea reduces the rate constant, disproving an exponential increase with Ea.

- \( \log k = \log A - \frac{E_a}{2.303RT} \)
- \( k = A e^{-\frac{E_a}{RT}} \)
- \( \ln k = -\frac{E_a}{RT} + \ln A \)
- \( k = A e^{\frac{E_a}{RT}} \)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The Arrhenius equation is k=Ae−Ea/RT. Option 4 is incorrect as it implies an exponential increase with Ea, contrary to the actual dependency, where higher Ea reduces the rate constant.
