(a)
Interpretation: Energy diagram that involves low energy for reactants and product while moderate-energy of intermediate should be drawn.
Concept introduction: Energetics of a reaction describes the energy associated with different components during the process of reaction. Energy diagram is a plot of energy along y-axis and reaction coordinate along x axis. Reaction proceeds when the reactant molecules collide and have proper orientation. The pathway from reactant to product involves transition state. A transition state is a hypothetical state that gives clear picture of the orientation of reactant molecules during collision that is a process of the bonds formed and broken during the reaction. Transition state is the highest energy state of a reaction.
The intermediate involved usually have higher potential energy than reactants species as they are formed transiently and fall back to form products that are more stable and hence reduced in potential energy.
