- Reaction coordinate diagrams: Two-step diagram. Label the reactant (R), product (P), intermediate (I"), and transition states (TS; and TS2), plus the axis with appropriate units/labels. 1) Break the diagram up into 2 steps. Which one is the slow step? The fast step? 2) Endothermic or exothermic? Suppose a is added to step one. Sketch the effect of this addition on the diagram. You can identify the intermediates and by remembering: Intermediates are and then Catalysts are added to a reaction (like a reactant), and are at the end. Practice: Identify the reactants, products, intermediate(s), and catalyst(s). Put a star next to the rate-determining step.
