Expert Solution

Step 1: Introduction

The progress of a reaction can be represented by the reaction coordinate diagram. In a reaction coordinate diagram, we can easily detect the transition state, activation energy, and intermediate.

Intermediate: The short-lived species which form in between the product and the reactants are known as intermediate.

Transition state: The highest energy species between the reactants and product or intermediate is known as a transition state.
