ANSWER:Solution:
In the above reaction-energy diagram, we have to label the reactants and the products and the activation energy for the first step and the second step.
Step 1
(a)Activation energy is defined as the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
The reactant species are generally represented in the left side where as the product species are represented in the right side.
The activation energy in the 1st step is represented by Ea1 and the activation energy in the 2nd step is represented by Ea2.
Thus the representation will be,
