Expert Answer:

Every reaction needs certain amount of minimum energy for the reaction to occur. This energy is called activation energy, Ea, and is expressed in kJ.
Activation energy is a positive quantity, Ea>0
It epends upon the nature of the reaction. "Fast" reactions usually have a small Ea; those with a large Ea usually proceed slowly.
Activation energy does not depend upon concentration of the reactants.
