potential energy diagram
use the potential energy diagram. what is shown by the letter a?
the activation energy of the forward reaction
the activation energy of the reverse reaction
the transition state
the heat of reaction
the entropy of the reaction

Explanation:

• The heat of reaction ($\Delta H$) is the difference in potential energy between the reactants and the products.
• In a potential - energy diagram, it is represented as the vertical distance between the reactant energy level and the product energy level.
• Activation energy (either forward or reverse) is the energy barrier (vertical distance from reactant or product to the transition state). The transition state is the peak of the energy curve. Entropy is a measure of disorder and is not directly represented as a vertical distance in a simple potential - energy diagram like this.

Answer:

the heat of reaction
