The exponential part of the Arrhenius equation expresses thefractionof reactant molecules that possess enough kinetic energy to react, as governed by the Maxwell-Boltzmann law. This fraction can run from zero to nearly unity, depending on the magnitudes of Eaand the temperature. If this fraction were unity, the Arrhenius law wouldreduceto k = A. In other words, A is the fraction of molecules that would react ifeither the activation energy were zero.

so answer is (3)
