The Arrhenius equation is:
Ak = A + E_a/RT
Bk = A × e^(+E_a/RT)
Ck = E_a/(RT)
Dk = A × e^(−E_a/RT)
Answer & Solution
Correct answer: D. k = A × e^(−E_a/RT)
**Arrhenius equation: k = A e^(−E_a/RT)**. A = frequency/pre-exponential factor. E_a = activation energy. The exponential e^(−E_a/RT) is the fraction of collisions with energy ≥ E_a.
