Question

Rate of a reaction can be expressed by Arrhenius equation as, $k=A{e}^{-E_a/RT}$. In this equation, $E_a$ represents

• A. The energy above which all the colliding molecules will react
• B. The energy below which colliding molecules will not react
• C. The total energy of the reacting molecules at a temperature $T$
• D. The fraction of molecules with energy greater than the activation energy of the reaction

Answer 1

Answer: (B)

The energy below which colliding molecules will not react

Rate of a reaction can be expressed by Arrhenium equation as, $k=A{e}^{\frac{-Ea}{Rt}},Ea\to$ the energy below which colliding molecules will not react.
