Question

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

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

Answer 1

The correct option is C The energy below which colliding molecules will not react

In the Arrhenius equation, E is for activation energy and it indicates the minimum amount of energy required for any reaction to proceed.
