Question

39.
Rate of a reaction can be expressed by Arrhenius equation
as: kr A e-E/RT. In this equation, E represents
(a) the total energy of the reacting molecules at a
temperature, T
(b) the fraction of molecules with energy greater than the
activation energy of the reaction
(c) the energy below which all the colliding molecules will
react
(d) the energy below which colliding molecules will not
react
of activation of the​

Answer 1

Answer:

E represents the energy of activation which implies it is the energy below which colliding molecules will not react

Arrhenius equation gives the dependence of the rate constant k of a chemical reaction on the absolute temperature T (in Kelvin), where A is the pre-exponential factor (or simply the prefactor), E

a

is the activation energy, and R is the Universal gas constant:

By Arrhenius equation, k=Ae
