question 4 (1 point)\npotential energy diagram\nuse the potential energy diagram. what is shown by the letter b?\nthe activation energy of the forward reaction\nthe activation energy of the reverse reaction\nthe transition state\nthe heat of reaction\nthe entropy of the reaction

Answer

Brief Explanations:

  • 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
