potential energy diagram
use the potential energy diagram. what is shown by the letter b?
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 is the energy barrier that reactants must overcome to form products. In a potential energy diagram, the activation energy of the forward reaction is the difference in potential energy between the reactants and the transition state.
• The transition state is the highest - energy point on the potential energy diagram.
• The heat of reaction (\(\Delta H\)) is the difference in potential energy between the products and the reactants (\(C\) in the diagram). Entropy is a measure of disorder and is not directly represented as a simple vertical distance in a basic potential - energy diagram of this type.
• For the forward reaction, the activation energy is the energy required to go from the reactant state to the transition state. In the given diagram, the vertical distance labeled \(B\) represents the activation energy of the forward reaction.

Answer:

the activation energy of the forward reaction
