In a reaction progress curve which point on the curve corresponds to an intermediate of the reaction?

In a reaction progress curve, the intermediate of the reaction is typically represented by a local maximum or a local minimum between the reactants and products. This point indicates a temporary state where the reactants have transformed but have not yet fully converted into the final products. The energy at this point is higher than that of the reactants and lower than that of the products, reflecting the stability of the intermediate before it proceeds to form the products.
