Question

which part of the diagram below represents the difference between the potential energy of the products and the potential energy of the reactants?

Answer 1

(D)

Step-by-step explanation

In the energy profile diagram, the difference in the potential energy between reactant and product is called enthalpy Change (ΔH).

Mathematically, Enthalpy Change (ΔH) = Heat of the product (Hₚ) – Heat of reactant (Hᵣ).

That is, ΔH = Hₚ – Hᵣ

Considering the diagram given in the question, the difference between the potential energy of the products and the potential energy of the reactants is indicated by the letter (D).
