Identify the correct expression of Arrhenius equation:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → $k = Ae^{-E_a/RT}$
The Arrhenius equation relates the rate constant k to the activation energy (Ea):
$k = A \, e^{-E_a / RT}$
- A = frequency factor
- R = gas constant
- T = temperature in Kelvin
- $E_a$ = activation energy
