Question

In the diagram shown above, which letter represents the potential energy of the products minus the potential energy of the reactants?

• A. B
• B. D
• C. A
• D. E
• E. C

Answer 1

The correct option is A B

In the diagram shown above, letter B represents the potential energy of the products minus the potential energy of the reactants. This energy difference corresponds to the enthalpy change
$\Delta H$ for the reaction.
