Answer:

Kindly find the attached image.

Explanation:

  • All the data related to the potential energy diagram is shown in the attached image.

Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).

  • Enthalpy change (ΔH) is the difference in energy between reactants and products.

ΔH = E of products - E of reactants.

Answer: Arrow E represents the enthalpy of the reaction.

Explanation:

Enthalpy of the reaction is defined as the difference in the potential energy of the products and the reactants. It is represented as [tex]\Delta H_{rxn}[/tex]

[tex]\Delta H_{rxn}=H_{products}-H_{reactants}[/tex]

From the image, the points marked represents:

Point A represents the potential energy of the reactants.

Point B represents the intermediate state or transition state in a reaction.

Point C represents the potential energy of the products.

Arrow D represents the activation energy of the reaction.

Arrow E represents the enthalpy of the reaction.

Hence, arrow E represents the enthalpy of the reaction.
