Which location represents the enthalpy of reaction?
2 answers:
Answer:
Kindly find the attached image.
Explanation:
- All the data related to the potential energy diagram is shown in the attached image.
<em>Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).</em>
<em />
- Enthalpy change (ΔH) is the difference in energy between reactants and products.
ΔH = E of products - E of reactants.
<u>Answer:</u> Arrow E represents the enthalpy of the reaction.
<u>Explanation:</u>
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.
