Question

Which location represents the enthalpy of reaction?

Answer 1

Answer:

Hope dat helps

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.

Enthalpy of the reaction is defined as the difference in the potential energy of the products and the reactants. It is represented as

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.
