Rate of a reaction can be expressed by Arrhenius equation as: k = Ae^(−E/RT) In this equation, E represents

the energy above which all the colliding molecules will react
the energy below which colliding molecules will not react
the total energy of the reacting molecules at a temperature, T
the fraction of molecules with energy greater than the activation energy of the reaction

Correct answer: the total energy of the reacting molecules at a temperature, T

Solution

The correct option describes E as the total energy of the reacting molecules at a given temperature, T, which is essential for understanding how temperature influences the rate of reaction according to the Arrhenius equation.
