Question

question 9 (1 point)
potential energy diagram
use the potential energy diagram. what is shown by the letter c?
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:

• Activation energy: The energy barrier that reactants must overcome to form products. In a potential energy diagram, it is the difference in energy between the reactants and the transition state (point B in this case).
• Transition state: The highest - energy state in the reaction pathway (point B).
• Heat of reaction ($\Delta H$): The difference in potential energy between the reactants and the products. In the given diagram, if we assume the initial level (before the rise to the transition state) represents reactants and the final level (after the reaction progress) represents products, then the vertical distance \(C\) is the heat of reaction.
• Entropy: A measure of disorder, not directly represented as a vertical distance in a simple potential - energy - vs - reaction - progress diagram.

Answer:

the heat of reaction
