Question

In the Arrhenius equation, $k=A e^{-E_{a} / R T}$, the factor $e^{-E_{a} / R T}$ corresponds to the

• A. fraction of molecules that have kinetic energy $=E_{a}$
• B. fraction of molecules that have kinetic energy $ > E_{a}$
• C. fraction of molecules that have kinetic energy $ < E_{a}$
• D. None of the above

Answer 1

Answer: (B)

In Arrhenius equation, $k=A e^{-E_{a} / R T}$, factor $e^{-E_{a} / R T}$ corresponds to the fraction of molecules that have kinetic energy $ > E_{a}$.
