Answer
The picture is attached below.
Work Step by Step
A reaction starts with a reactant and ends with a product as labelled in the diagram below. For the first step, the activation energy (Ea1) is the energy required by the reactants to reach a transition state, that is the peak of the curve. For the second step, the activation energy (Ea2) is the energy required by the intermediates formed to reach another transition state, that is the second peak of the reaction curve.
